Joel is 5 years old and his dad is 32 years old. How old will Joel be when his dad is twice as old as him?
The difference in age between Joel and his dad is 32 - 5 =
<<32-5=27>>27 years. When you double this gap in years, you have 27 x 2 = <<27*2=54>>54. When his dad is 54, Joel will be 54 / 2 = <<54/2=27>>27 years old. #### 27 Will and Henry go fishing in a river. Will catches 16 catfish and 10 eels. Henry challenges himself to catch 3 trout for every catfish Will catches. Due to environmental concerns, Henry decides to return half his catch after meeting his own challenge. How many fishes do they have altogether now? Will caught 16+10= <<16+10=26>>26 fishes Henry caught 3 trout for each catfish Will caught so since Will caught 16 catfish, Henry caught 16*3 = <<3*16=48>>48 trout Half of 48 trout is (1/2)*48 = 24 Henry returned 24 trout leaving him with 48-24 = <<48-24=24>>24 trout They now have a total of 26+24 = <<26+24=50>>50 fishes #### 50 Henry drinks 15 bottles of kombucha every month. Each bottle costs $3.00 and is eligible for a cash refund of $0.10 per bottle when he takes it to a recycling center. After 1 year, how many bottles of kombucha will he be able to buy after he receives his cash refund? He drinks 15 bottles every month and there are 12 months in 1 year so that's 15*12 = <<15*12=180>>180 bottles He earns $0.10 on every bottle that he recycles so that's .10*180 = $<<.10*180=18.00>>18.00 He has $18.00 and each bottle costs $3.00 so he can buy 18/3 = <<18/3=6>>6 bottles #### 6 On Friday, Markeesha sold 30 boxes of crackers for her scout troop's fundraiser. On Saturday, she sold twice as many as on Friday. On Sunday, she sold 15 fewer than Saturday. How many boxes did she sell over the three days? On Saturday, she sold 2*30=<<2*30=60>>60 boxes. On Sunday, she sold 60-15=<<60-15=45>>45 boxes. She sold a total of 30+60+45=<<30+60+45=135>>135. #### 135 In Fred the Farmer's barn, there were 100 horses, 29 sheep, and 9 chickens. Brian bought half of the animals and sold them at the market. Jeremy then gifted Fred an additional 37 goats. If exactly half of the animals in the barn are male animals, how many male animals are there in the barn? Fred's barn started with 100 + 29 + 9 = <<100+29+9=138>>138 animals. Brian bought half of these, so there were 138 / 2 = <<138/2=69>>69 remaining. After Jeremy gifted Fred 37 goats, there were 69 + 37 = <<69+37=106>>106 animals in the barn. So, 106 / 2 = <<106/2=53>>53 of these animals are male. #### 53 Saturday at the ice cream shop, there were twice as many people who ordered vanilla ice cream as ordered chocolate ice cream. If 220 people ordered ice cream on Saturday, and 20% of those ordered vanilla ice cream, how many people ordered chocolate ice cream? If 20% of 220 customers ordered vanilla, then there were 0.2*220=<<0.2*220=44>>44 customers who ordered vanilla. If there were twice as many people who ordered vanilla as chocolate, then 44/2=<<44/2=22>>22 customers ordered chocolate. #### 22 Lara bought 52 stems of flowers at the flower shop. She gave 15 flowers to her mom and gave 6 more flowers than she gave to her mom to her grandma. She put the rest in a vase. How many stems of flowers did Lara put in the vase? Lara gave 15 + 6 = <<15+6=21>>21 stems of flowers to her grandma. She gave away 21 + 15 = <<21+15=36>>36 stems of flowers. Therefore, Lara put 52 - 36 = <<52-36=16>>16 stems of flowers in the vase. #### 16 It takes Polly 20 minutes to cook breakfast every day. She spends 5 minutes cooking lunch. She spends 10 minutes cooking dinner 4 days this week. The rest of the days she spends 30 minutes cooking dinner. How many minutes does Polly spend cooking this week? Polly spends 20*7 =<<20*7=140>>140 minutes cooking breakfast. She spends 5*7= <<5*7=35>>35 minutes cooking lunch. She spends (10*4)+(30*3)= <<10*4+30*3=130>>130 minutes cooking dinner. Therefore, she spends 140+35+130=<<140+35+130=305>>305 minutes cooking this week. #### 305 Robert had 25 balls. Tim gave him half of his 40 balls. How many balls does Robert have now? Tim gave 40 / 2 = <<40/2=20>>20 balls to Robert. Robert now has 25 + 20 = <<25+20=45>>45 balls. #### 45 Linda makes and sells necklaces at craft fairs. At her most recent fair she sold 4 necklaces and 8 rings for a total of $80. If each necklace costs $12, how much does each ring cost? Let’s use r for the cost of each necklace 4*12+8*r=80 48+8*r=80 8*r=80-48=32 8r=32 r=<<4=4>>4 dollars for each ring #### 4
