Josh has 9 dollars. He spent $1.75 on a drink, and then spent another $1.25. How much money, in dollars, does Josh have left?

Josh spent 1.75+1.25=

<<1.75+1.25=3>>3 dollars in total. Josh has 9-3=<<9-3=6>>6 dollars left. #### 6 Max can mow the lawn in 40 minutes. If it takes him twice that long to fertilize the lawn, how long will it take him to both mow and fertilize the lawn? It takes Max 2 * 40 minutes = <<2*40=80>>80 minutes to fertilize the lawn. In total, Max takes 80 minutes + 40 minutes = <<80+40=120>>120 minutes to both mow and fertilize the lawn. #### 120 Diana gets 30 minutes of video game time for every hour she reads. Her dad decided to raise her reward by 20%. Diana read for 12 hours this week. How many more minutes of video game time will she get as a result of her raise? Diana’s raise was 20% of her 30-minute video game time, or 0.20 x 30 minutes = <<20*.01*30=6>>6 minutes. Diana is now making 30 minutes + 6-minute raise = <<30+6=36>>36 minutes for every hour she reads. Diana read 12 hours x 36 minutes of video game time, so she received 432 minutes of video game time after her raise. Before, if Diana read 12 hours x 30 minutes of video game time, she would have received 360 minutes. The amount she received after her raise, 432 minutes – 360 minutes at her old rate = <<432-360=72>>72 more minutes after her raise. #### 72 A school cafeteria uses ground mince to cook lasagnas and cottage pies. They make 100 lasagnas, which use 2 pounds of ground mince each, and cottage pies, which use 3 pounds of ground mince each. If the cafeteria has used 500 pounds of ground mince in total, how many cottage pies did they make? The cafeteria used 100 lasagnas * 2 pounds of ground mince = <<100*2=200>>200 pounds of ground mince for the lasagnas. This means they used 500 pounds of ground mince in total – 200 pounds of ground mince for the lasagnas = 300 pounds of ground mince for the cottage pies. So they must have made 300 pounds of ground mince for the cottage pies / 3 pounds of ground mince per cottage pie = <<300/3=100>>100 cottage pies. #### 100 On the first day of school, Mrs. McGillicuddy had 25 students registered for the morning session of kindergarten, but 3 students were absent; and she had 24 students registered for the afternoon session, but 4 students were absent. How many students did Mrs. McGillicuddy have over the two kindergarten sessions? 25-3=<<25-3=22>>22 students 24-4=<<24-4=20>>20 students She had 22+20=<<22+20=42>>42 students #### 42 An air conditioner running for eight hours would consume 7.2 kilowatts. How many kilowatts would the air conditioner consume if it was used for 6 hours a day for 5 days? The air conditioner consumes 7.2/8 = <<7.2/8=0.9>>0.9 kilowatt per hour. So, in 6 hours, it will consume 0.9 kilowatts per hour * 6 hours = <<0.9*6=5.4>>5.4 kilowatts. In 5 days, its total consumption is 5.4 kilowatts * 5 = <<5.4*5=27>>27 kilowatts. #### 27 Gary is restocking the grocery produce section. He adds 60 bundles of asparagus at $3.00 each, 40 boxes of grapes at $2.50 each, and 700 apples at $0.50 each. How much is all the produce he stocked worth? First find the total cost of the asparagus: 60 bundles * $3/bundle = $<<60*3=180>>180 Then find the total cost of the grapes: 40 boxes * $2.50/bundle = $<<40*2.5=100>>100 Then find the total cost of the apples: 700 apples * $0.50/apple = $<<700*0.5=350>>350 Then add the cost of each type of food to find the total cost of the produce: $180 + $100 + $350 = $<<180+100+350=630>>630 #### 630 The price of two kilograms of sugar and five kilograms of salt is $5.50. If a kilogram of sugar costs $1.50, then how much is the price of three kilograms of sugar and a kilogram of salt? Two kilograms of sugar is priced at $1.50 x 2 = $<<2*1.5=3>>3. Three kilograms of sugar is priced at $1.50 x 3 = $<<3*1.5=4.50>>4.50. So five kilograms of salt is priced at $5.50 - $3 = $2.50. Thus, a kilogram of salt is priced at $2.50/5 = $<<2.5/5=0.50>>0.50. Hence, three kilograms of sugar and a kilogram of salt.s price is $4.50 + $0.50 = $5. #### 5 A train leaves its departure station with 6 coal cars, 12 iron cars, and 2 wood cars. Between each station, there are 6 miles, and it takes 25 minutes to travel between them. At each station, the train can deposit up to 2 coal cars, 3 iron cars, and 1 wood car. How many minutes will it take to deliver all the cars? To deliver all the coal, you need to pass by 6 coal / 2 coal/station = <<6/2=3>>3 stations To deliver all the iron, you need to pass by 12 iron / 3 iron/station = <<12/3=4>>4 stations To deliver all the wood, you need to pass by 2 wood / 1 wood/station = <<2=2>>2 stations So 4 stations are needed to deliver everything, so 4 stations * 25 minutes/station = <<4*25=100>>100 minutes are needed #### 100 John watches a TV show and they announce they are going to do 1 more season. Each season is 22 episodes except for the last season which is 4 episodes longer. There were 9 seasons before the announcement. If each episode is .5 hours how long will it take to watch them all after the last season finishes? There are currently 9*22=<<9*22=198>>198 episodes out The new season will have 22+4=<<22+4=26>>26 episodes So the total number of episodes is 198+26=<<198+26=224>>224 episodes So it will take 224*.5=<<224*.5=112>>112 hours to watch them all #### 112
