A cobbler can mend 3 pairs of shoes in an hour. From Monday to Thursday, the cobbler works for 8 hours each day, and on Friday, he only works from 8am to 11am. How many pairs of shoes can the cobbler mend in a week?

From Monday to Thursday, the cobbler can mend 3 x 8 =

<<3*8=24>>24 pairs of shoes a day. From Monday to Thursday, he can mend 24 x 4 = <<24*4=96>>96 pairs of shoes. On Friday, he works for 11 - 8 = <<11-8=3>>3 hours. On Friday, he can mend 3 x 3 = <<3*3=9>>9 pairs of shoes. In a week, he can mend 96 + 9 = <<96+9=105>>105 pairs of shoes. #### 105 John is 10 years old. His sister is twice his age. When he is 50 years old, how old will his sister be? His sister is 10*2= <<10*2=20>>20 years old Their age difference is 20-10= <<20-10=10>>10 years Therefore when he is 50 she will be 50+10= <<50+10=60>>60 years old. #### 60 You draw a rectangle that is 7 inches wide. It is 4 times as long as it is wide. What is the area of the rectangle? The length of the rectangle is 4 * 7 inches = <<4*7=28>>28 inches. The area of the rectangle is 7 inches * 28 inches = <<7*28=196>>196 square inches. #### 196 Erwin eats 2 chocolates on weekdays and 1 chocolate on weekends. He ate 24 chocolates in total. How many weeks did it take to finish all the chocolate? On weekdays he eats 5*2=<<5*2=10>>10 chocolates On weekends he eats 2*1=<<2*1=2>>2 chocolates He eats 10+2=<<10+2=12>>12 chocolates in a week. It takes 24/12=<<24/12=2>>2 weeks to finish all the chocolate. #### 2 Alexa has a lemonade stand where she sells lemonade for $2 for one cup. If she spent $20 on ingredients, how many cups of lemonade does she need to sell to make a profit of $80? To make a profit of $80, she needs to make $80 + $20 = $<<80+20=100>>100 She needs to sell $100 / $2 = <<100/2=50>>50 cups of lemonade #### 50 Janet's grades for her first semester of college were 90, 80, 70, and 100. If her semester 2 average was 82 percent, how much higher was her semester 1 average compared to her semester 2 average? First add all Janet's grade for the first semester of college: 90 + 80 + 70 + 100 = <<90+80+70+100=340>>340 Then divide that number by 4 to find her average grade: 340 / 4 = <<340/4=85>>85 Then subtract her semester 2 average to find the difference: 85 - 82 = <<85-82=3>>3 #### 3 Keegan is in school for 7.5 hours each day and he is taking 7 classes. He has history and chemistry classes for a combined total of 1.5 hours. How many minutes does Keegan spend in one of his other classes on average? He has 7-2=<<7-2=5>>5 other classes 7.5 hours - 1.5 hours = <<7.5-1.5=6>>6 hours 6 hours = <<6*60=360>>360 minutes 360/5 = <<360/5=72>>72 minutes Keegan spends 72 minutes in one of his other classes. #### 72 Lennon is a sales rep and is paid $0.36 in mileage reimbursement when he travels to meet with clients. On Monday he drove 18 miles. Tuesday he drove 26 miles. Wednesday and Thursday he drove 20 miles each day and on Friday he drove 16 miles. How much money will he be reimbursed? In one week he drove 18+26+20+20+16 = <<18+26+20+20+16=100>>100 miles He is reimbursed $0.36 per mile of travel, and he travels 100 miles so he will receive .36*100 = $<<.36*100=36.00>>36.00 #### 36 It will take Richard and Sarah 3 years to save enough for a down payment on a house at their current rates. If the house's downpayment is $108000, calculate the amount each person saves per month if they share the monthly savings. If they are to save every month for three years to reach the target amount, and each year has 12 months, they'll save for 12*3 = <<12*3=36>>36 months. If the house's downpayment is $108000, the total amount they both save per month is $108000/36 = $<<108000/36=3000>>3000 every month. Since they share the monthly savings, each person will pay $3000/2= =$<<3000/2=1500>>1500 #### 1500 Ashley had already blown up 12 balloons for the party when Andy took over and started blowing them up at a rate of 2 every five minutes. When Andy stopped, there were 50 balloons. For how many minutes did Andy blow up balloons? Andy blew up 50 balloons – the 12 balloons Ashley blew up = <<50-12=38>>38 balloons. We know how long it took Andy to blow up 2 balloons, so 38 balloons / 2 = <<38/2=19>>19 time increments. We know the time increment is 5 minutes, so 19 x 5 minutes = <<19*5=95>>95 minutes. #### 95
