In a car dealership with 600 cars, 60% of the cars are hybrids, and 40% of the hybrids contain only one headlight. How many of the hybrids have full headlights?

In the car dealership with 600 cars, 60% of the cars are hybrids, meaning there are 60/100*600 =

<<60/100*600=360>>360 hybrid cars. Out of the 360 hybrid cars, 40% contain only one headlight. a total of 40/100*360 = <<40/100*360=144>>144 cars. The total number of hybrid cars with full headlights is 360-144=<<360-144=216>>216 #### 216 Troy is thinking of buying a new computer that is worth $80. He has initially saved $50 and plans to sell his old computer for $20. How much more money does he need so he could buy the new computer? Troy has $50 + $20 = $<<50+20=70>>70 from his savings and the sales of his old computer. Therefore, he still needs $80 - $70 = $<<80-70=10>>10 more to buy the new computer. #### 10 A grocery store has 4 kinds of jelly. They sell grape jelly twice as much as strawberry jelly, and raspberry jelly twice as much as plum jelly. The raspberry jelly sells a third as much as the grape jelly. If they sold 6 jars of plum jelly today, how many jars of strawberry jelly did they sell? They sell twice as much raspberry jelly as plum jelly, so they sold 2 * 6 = <<2*6=12>>12 jars of raspberry jelly today. The raspberry jelly sells a third as much as the grape jelly, so they sold 12 * 3 = <<12*3=36>>36 jars of grape jelly today. The grape jelly sells twice as much as the strawberry jelly, so they sold 36 / 2 = <<36/2=18>>18 jars of strawberry jelly today. #### 18 Elois needs 4 bananas to make 1 loaf of banana bread. On Monday, she makes 3 loaves of banana bread. On Tuesday, she makes twice as many loaves of banana bread as Monday. How many bananas did she use to make all the banana bread? On Tuesday, Elois makes 3 x 2 = <<3*2=6>>6 banana breads. She makes a total of 3 + 6 = <<3+6=9>>9 banana breads. She uses 9 x 4 = <<9*4=36>>36 bananas to make all the banana breads. #### 36 Michelle uses 40 beads in making a necklace. She uses 5 blue beads and 2 times as many red beads as blue beads. Then she uses the same number of white beads as the blue and red beads combined. If the rest of the beads she uses are silver, how many silver beads does she use? Michelle uses 5 x 2 = <<5*2=10>>10 red beads. She uses 5 + 10 = <<5+10=15>>15 white beads. So she uses a total of 5 + 10 + 15 = <<5+10+15=30>>30 blue, red, and white beads. Therefore, she uses 40 - 30 = <<40-30=10>>10 silver beads. #### 10 James injured his ankle and decides to slowly start working back up to his previous running goals and then surpass them. Before the injury, he was able to run 100 miles per week. He wants to get up to 20% more than that total in 280 days and each week he will increase miles walked in the week by the same amount. How many miles does he need to add per week? He wants to run 100*.2=<<100*.2=20>>20 miles more than he used to So he needs to run 100+20=<<100+20=120>>120 miles He is doing this in 280/7=<<280/7=40>>40 weeks So he needs to add 120/40=<<120/40=3>>3 miles per week #### 3 Danielle wants to make her own popsicles. She finds out she needs popsicle sticks, molds, and juice. She has $10 for supplies. She buys one set of molds for $3 and a pack of 100 popsicle sticks for $1. Each bottle of juice makes 20 popsicles and costs $2. How many popsicle sticks will she be left with if she makes as many as she can? She has $6 left after buying initial supplies because 10 - 3 -1 = <<10-3-1=6>>6. She can buy 3 bottles of juice because 6 / 2 = <<6/2=3>>3. She can make 60 popsicles because 20 x 3 = <<20*3=60>>60 She has 40 sticks left because 100 -6 60 = 40 #### 40 A fisherman catches 3 types of fish in his net. There are 32 bass, 1/4 as many trout as bass, and double the number of blue gill as bass. How many fish did the fisherman catch total? Bass:32 Trout:32/4=8 Blue Gill:2(32)=<<64=64>>64 Total:32+8+64=<<32+8+64=104>>104 fish #### 104 It takes 20 minutes for John to go to the bathroom 8 times. How long would it take to go 6 times? He spends 20/8=<<20/8=2.5>>2.5 minutes each time he goes in So it would take 2.5*6=<<2.5*6=15>>15 minutes to go 6 times #### 15 June made a design with 20 equal tiles. Three tiles are yellow and the number of blue tiles is one more than the number of yellow tiles. Six tiles are purple and the remaining tiles are white. How many white tiles are there? There are 3 + 1 = <<3+1=4>>4 blue tiles. There are a total of 3 + 4 + 6 = <<3+4+6=13>>13 tiles are yellow, blue, and purple. Hence, 20 - 13 = <<20-13=7>>7 tiles are white. #### 7
