John's car needs a new engine. The labor costs $75 an hour for 16 hours. The part itself cost $1200. How much did the repairs cost in total?

The labor cost 16*$75=$

<<16*75=1200>>1200 So the total cost was $1200+$1200=$<<1200+1200=2400>>2400 #### 2400 Teddy is a pillow-maker. He uses 3 less than 5 pounds of fluffy foam material to make each pillow. If Teddy has three tons of fluffy foam material, how many pillows can he make? Three less than 5 is 5-3=<<5-3=2>>2. Since one ton is 2000 pounds, three tons is 2000*3=<<6000=6000>>6000 pounds. Thus, in 6000 pounds, he can make 6000/2=<<6000/2=3000>>3000 pillows. #### 3,000 Tom rents a helicopter for 2 hours a day for 3 days. It cost $75 an hour to rent. How much did he pay? He rented the helicopter for 2*3=<<2*3=6>>6 hours So he paid 6*75=$<<6*75=450>>450 #### 450 Tricia ordered three dozen eggs. She will use 1/4 of them for making crepes, and 2/3 of the remaining for making cupcakes. How many eggs are left to make sunny-side-up eggs for breakfast? Since a dozen is equal to 12, then 3 dozen eggs are equal to 12 x 3 = <<3*12=36>>36 eggs. Tricia will use 36 x 1/4 = <<36*1/4=9>>9 eggs for making crepes. So there are 36 - 9 = <<36-9=27>>27 eggs left. 27 x 2/3 = <<27*2/3=18>>18 eggs will be used for making cupcakes. Thus, there are only 27 - 18 = <<27-18=9>>9 eggs left to make sunny-side-up eggs for breakfast. #### 9 Heather helps her neighbour pick weeds out of her garden. She gets paid 5 cents for every weed she picks. On average, how many seconds can she take to pick a weed if she wants to earn $10 an hour? In an hour, she needs to earn $10 * 100 cents / $1 = <<10*100=1000>>1000 cents. In an hour, she must pick 1000 cents / 5 cents = <<1000/5=200>>200 weeds. There are 1hr * (60 minutes / 1 hr) = <<1*60=60>>60 minutes in an hour. There are 60 minutes * (60 seconds / 1 minute) = <<60*(60/1)=3600>>3600 seconds in an hour. She has 3600 seconds / 200 = <<3600/200=18>>18 seconds to pick each weed. #### 18 Kim has 12 nail polishes. Heidi has 5 more nail polishes than Kim, and Karen has 4 fewer nail polishes than Kim. How many nail polishes does Karen and Heidi have together? Heidi has 12+5 = <<12+5=17>>17 nail polishes. Karen has 12-4 = <<12-4=8>>8 nail polishes. Heidi and Karen have 17+8 = <<17+8=25>>25 nail polishes together. #### 25 Hannah has three brothers. Her brothers are all 8 years old. How old is Hannah if she is twice as old as the sum of her brother's ages? The total of Hannah's brothers' ages is 3 * 8 = <<3*8=24>>24. Hannah is twice as old as the total of her brothers' ages, so Hannah is 24 * 2 = <<24*2=48>>48 years old. #### 48 Mr. Johnson is organizing the school Christmas play and needs 50 volunteers to help with decorating the auditorium. 5 students from each of the school’s 6 math classes have volunteered to help. 13 teachers have also volunteered to help. How many more volunteers will Mr. Johnson need? Since 5 students from each of the 6 math classes have volunteered, there are 5*6= <<5*6=30>>30 total student volunteers. In addition to the 30 student volunteers, 13 teachers have also volunteered so there are 30+13= <<30+13=43>>43 total volunteers. Mr. Johnson needs 50 volunteers and currently has 43 volunteers, so he needs 50-43= <<50-43=7>>7 more volunteers. #### 7 Pat is buying supplies for S'mores. He and his friends will each eat 3 S'mores. There are 8 of them in total. It costs $3 in supplies to make 4 S'mores. How much will it cost to buy all the supplies? They are making 24 S'mores because 8 x 3 = <<8*3=24>>24 Each S'more costs $.75 to make because 3 / 4 = <<3/4=.75>>.75 It will cost $18 to make them all because 24 x .75 = <<24*.75=18>>18 #### 18 Pat is hunting for sharks to take photos. For every photo he takes he earns $15. He sees a shark about every 10 minutes. His boat fuel costs $50 an hour. If he shark hunts for 5 hours, how much money can he expect to make in profit? He will use $250 in fuel because 5 x 50 = <<5*50=250>>250 He will be shark hunting for 300 minutes because 5 x 60 = <<5*60=300>>300 He can expect to see 30 sharks because 300 / 10 = <<300/10=30>>30 He will make $450 off these photos because 30 x 15 = <<30*15=450>>450 He will make $200 in profit because 450 - 250 = <<450-250=200>>200 #### 200
