Ivar owns a stable. He recently has 3 horses and each horse consumes 5 liters of water for drinking and 2 liters for bathing per day. If he added 5 horses, how many liters of water does Ivar need for all the horses for 28 days?

The total horse he owns is 5+3=

<<5+3=8>>8. The total liters of water each horse consumes is 5 + 2= <<5+2=7>>7. So, the total water all the horses consume every day is 7 x 8 = <<7*8=56>>56. And the total of liters of water they consume every week is 56 x 7 = <<56*7=392>>392. Therefore, the total liters of water they consume for the entire month is 392 x 4= <<392*4=1568>>1568. #### 1568 Trevor and Joe were working together to finish a 500 piece puzzle. They put the border together first and that was 75 pieces. Trevor was able to place 105 pieces of the puzzle. Joe was able to place three times the number of puzzle pieces as Trevor. How many puzzle pieces are missing? The puzzle is 500 pieces and the border used 75 pieces so 500-75 = <<500-75=425>>425 pieces left Joe placed three times as many puzzle pieces as Trevor who placed 105 so Joe placed 3*105=315 piece Together Joe and Trevor placed 315+105 pieces for a total of <<315+105=420>>420 pieces With the border down that left 425 pieces left and they put down 420 pieces so that meant 425-420 = <<425-420=5>>5 pieces were missing #### 5 Ariana is past due on three bills. The first bill for $200 charges 10% simple interest for each overdue month and it's 2 months overdue. The second bill for $130 charges a flat $50 late fee per month and is 6 months overdue. The last bill is two months late and charges a $40 fee the first month overdue and twice that fee the second month overdue and is for $444. How much does Ariana owe in total? First find the monthly late fee for the first bill: $200 * 10% = $<<200*10*.01=20>>20 Then multiply that by the number of months the bill is overdue: $20/month * 2 months = $<<20*2=40>>40 Then find the total late fee for the second bill the same way: $50/month * 6 months = $<<50*6=300>>300 Then find the third bill's second late fee: 2 * $40 = $<<2*40=80>>80 Then add all the bill amounts and late fees to find the total cost: $40 + $200 + $300 + $130 + $40 + $80 + $444 = $<<40+200+300+130+40+80+444=1234>>1234 #### 1234 Alex has not washed his clothes for a month; 18 shirts, 12 pants, 17 sweaters, and 13 jeans are waiting to be washed. Alex's washing machine can wash a maximum of 15 items per cycle. Each cycle takes 45 minutes. How many hours will it take the washing machine to wash all the clothes? Alex will wash 18 + 12 + 17 + 13 = <<18+12+17+13=60>>60 items. With 20 items per wash cycle, Alex will wash the clothes in 60 / 15 = 4 cycles. With 45 minutes per cycle, the washing machine will take 45 * 4 = <<45*4=180>>180 minutes to wash the clothes. As 1 hour has 60 minutes, the washing machine will take 180 / 60 = <<180/60=3>>3 hours to wash the clothes. #### 3 Of the 100 soccer balls that Nova went to inflate, 40 percent had holes in them and could not inflate, while 20% of the remaining balls were overinflated and exploded. How many balls were inflated successfully and could be used? If 40% of the balls had holes in them and could not inflate, their number was 40/100*100= <<40/100*100=40>>40 The remaining balls that Nova could inflate were 100-40 = <<100-40=60>>60 While inflating, 20% of the good soccer balls were overinflated and exploded up, a total of 20/100*60 = <<20/100*60=12>>12 The number of soccer balls that inflated successfully and could be used is 60-12 = <<60-12=48>>48 #### 48 Jacob is building ladders. One of his clients needs 10 ladders with 50 rungs, and 20 ladders with 60 rungs. Jacob has to charge $2 for every rung. How much does the client have to pay for the ladders? 10 ladders with 50 rungs have a total of 10*50=<<10*50=500>>500 rungs. 20 ladders with 60 rungs have a total of 20*60=<<20*60=1200>>1200 rungs. In total there are 1200+500=<<1200+500=1700>>1700 rungs. The client must pay 2*1700=$<<2*1700=3400>>3400. #### 3,400 For an operations manager job at a company, a person with a degree earns three times the amount paid to a diploma holder for the same position. How much will Jared earn from the company in a year after graduating with a degree if the pay for a person holding a diploma certificate is $4000 per month? Since the pay for a person holding a degree is three times the amount paid for a diploma holder, Jared will earn 3*$4000 = $<<4000*3=12000>>12000 per month. In a year with 12 months, Jared will earn a total of 12*12000 = <<12*12000=144000>>144000 #### 144000 Casey is trying to decide which employee she wants to hire. One employee works for $20 an hour. The other employee works for $22 an hour, but Casey would also get a $6/hour subsidy from the government for hiring a disabled worker. How much money per week would Casey save by hiring the cheaper employee, if they both work 40 hours per week? First find the weekly cost of the first employee: $20/hour * 40 hours/week = $<<20*40=800>>800/week Then find the hourly cost of the second employee after the government subsidy: $22/hour - $6/hour = $<<22-6=16>>16/hour Then find the weekly cost of the second employee: $16/hour * 40 hours/week = $<<16*40=640>>640/week Then subtract the smaller weekly cost from the bigger weekly cost to find the difference: $800/week - $640/week = $<<800-640=160>>160/week #### 160 Since 1989, Lily has treated herself to 1 hydrangea plant, each year. Each plant costs $20.00. By 2021, how much money has Lily spent on hydrangeas? She started buying plants in 1989 and it's now 2021 so she has bought these plants for 2021-1989 = <<32=32>>32 years Each plant costs $20.00 and she has bought them for 32 years so she has spent 20*32 = $<<20*32=640.00>>640.00 on hydrangeas #### 640 Emmalyn decided to paint fences in her neighborhood for twenty cents per meter. If there were 50 fences in the neighborhood that she had to paint and each fence was 500 meters long, calculate the total amount she earned from painting the fences. The total length for the fifty fences is 50*500 = <<50*500=25000>>25000 meters. If Emmalyn charged twenty cents to paint a meter of a fence, the total income she got from painting the fences is $0.20*25000 =$5000 #### 5000
