Tonya spent $90.00 on art supplies. 4 canvases cost $40.00 and a mixed set of paints cost 1/2 that much. She also spent $15.00 on an easel, and the rest of the money on paintbrushes. How much money did she spend on paintbrushes?

The canvases cost $40.00 and she spent half that amount on paint so she spent 40/2 = $

<<40/2=20.00>>20.00 on paint She spent $40.00 on canvases, $20.00 on paint and $15.00 on an easel so she spent 40+20+15 = $<<40+20+15=75.00>>75.00 She spent $90.00 total and her other purchases totaled $75.00 so she spent 90-75 = $<<90-75=15.00>>15.00 on paint brushes #### 15 Rita put a $120 elliptical machine on layaway at her local sports good store. After making a down payment equal to half the cost of the machine, she completely forgot about it. Sometime before the pick-up date, a store employee called offered to waive all layaway fees and taxes on the condition that Rita paid the balance within 10 days. What is the daily minimum amount, in dollars, that Rita must pay to own the elliptical machine? The down payment Rita made was 120/2 = <<120/2=60>>60 dollars. The balance was therefore 120 - 60 = <<120-60=60>>60 dollars. To pay off the balance within 10 days, Rita must make payments of 60/10 = <<60/10=6>>6 dollars per day #### 6 In the class of 24 students, half are doing silent reading, and a third are playing board games. The rest are catching up on homework. How many students are catching up on homework? 24/2=<<24/2=12>>12 students are doing silent reading. 24/3=<<24/3=8>>8 students are playing board games. So 12+8=<<12+8=20>>20 students are accounted for. Then 24-20=<<24-20=4>>4 students are catching up on homework. #### 4 Jay went to watch a singer in a one hour 20 minutes concert. If there was a 10-minute intermission, and all the songs were 5 minutes except for one song that lasted 10 minutes, how many songs did she sing? The time the singer had for singing was 80 - 10 = <<80-10=70>>70 minutes. The time the singer had for singing 5-minute songs was 70 - 10 = 60 minutes. The number of 5-minute songs was 60 / 5 = <<60/5=12>>12 songs. The total number of songs sung is 12 + 1 = <<12+1=13>>13 songs. #### 13 Helen cuts her lawn starting in March and finishes in October. Her lawn mower uses 2 gallons of gas every 4th time she cuts her lawn. For March, April, September and October, she only cuts her law 2 times per month. In May, June, July and August, she has to cut her lawn 4 times per month. How many gallons of gas will she need to cut her lawn from March through October? For March, April, September and October, she cuts her lawn 2 a month. There are 4 months so she cuts her yard 2*4 = <<2*4=8>>8 times For May, June, July and August, she cuts her lawn 4 times a month. There are 4 months so she cuts her yard 4*4 = <<4*4=16>>16 times During the entire 8 month period, she cuts her lawn 8+16 = <<8+16=24>>24 times Every 4th time she cuts, she needs 2 gallons of gas. If she cuts her lawn 24 times a year then she needs to fill up 24/4 = 6 times Each time she fills up, it takes 2 gallons of gas so 2*6 = <<2*6=12>>12 gallons of gas per year #### 12 Minnie is making a playlist of songs for a party she will be throwing. She wants the playlist to be an hour long. She has added 16 three-minute songs to the playlist. How many four-minute songs does she have to add to make sure the playlist is an hour long? An hour is equal to 60 minutes. Minnie has 16 * 3 = <<16*3=48>>48 minutes of songs already on the playlist. She has to fill 60 - 48 = <<60-48=12>>12 more minutes. Thus, she needs to add 12 / 4 = <<12/4=3>>3 four-minute songs. #### 3 Denmark wants to order pizza. For toppings, he has 3 cheese, 4 meat and 5 vegetable options, one of which is peppers. He can have only one selection from each topping category (one cheese, one meat and one vegetable). However, if he chooses to have pepperoni, he cannot have peppers. How many topping combinations does he have total? Permutate the ingredients. 3 cheeses * 4 meats * 5 vegetables = <<3*4*5=60>>60 choice However, we must take out the combinations that could have pepperoni and peppers, 1 cheese +1 meat *+1 vegetable = <<1+1+1=3>>3 bad choices 60 - 3 = <<60-3=57>>57 choices #### 57 Jason is making sand art. He wants to fill a rectangular patch 6 inches by 7 inches with blue sand, and a square path 5 inches by 5 inches with red sand. If it takes 3 grams of sand to fill one square inch, how many grams of sand does Jason need? First find the area of the first patch: 6 inches * 7 inches = <<6*7=42>>42 inches Then find the area of the second patch: 5 inches * 5 inches = <<5*5=25>>25 inches Then add those two amounts to find the total area Jason needs to cover: 42 inches + 25 inches = <<42+25=67>>67 inches Then multiply that area by the number of grams per square inch to find the total amount of sand needed: 67 inches * 3 grams/square inch = <<67*3=201>>201 grams #### 201 Jack has been driving for the past 9 years. He drives 37,000 miles every four months. How many miles has Jack driven since he started driving? There are 12/4 = <<12/4=3>>3 four month groups in a year Jack drives 37,000*3 = <<37000*3=111000>>111,000 miles in a year. Jack has driven 111,000*9 = <<111000*9=999000>>999,000 miles since he has started driving. #### 999,000 To get ready for the new school year, Mary brought her two kids shopping. She bought her son James, a coat for $40 and two pairs of jeans. She bought his sister Jamie, a pair of shoes for $30. The total cost of the items was $110. If the two pairs of jeans for James cost the same price, how much did one pair of jeans cost? The total spent on both pairs of jeans was $110 - $40 - $30 = $<<110-40-30=40>>40. One pair of jeans would cost $40 / 2 = $<<40/2=20>>20. #### 20
