Susie and Britney each keep chickens, of two different breeds. Susie has 11 Rhode Island Reds and 6 Golden Comets. Britney has twice as many Rhode Island Reds as Susie, but only half as many Golden Comets. How many more chickens are in Britney's flock than in Susie's?
Let's think: Britney has 11 * 2 = 22 Rhode Island Reds. She has 6 / 2 = 3 Golden Comets. She has 22 + 3 = 25 total. Susie has 11 + 6 = 17 total. Britney has 25 - 17 = 8 more.. The answer is: 8.

Steve owns a lake shop that sells fish. He has a stock of 200 fish. He sells 50 fish and because his refrigerators stop working a third of the remaining fish become spoiled. A new stock of 200 more fish arrives. How many fish does he have in stock now?
Let's think: If he had 200 fish and sells 50, he is left with 200 - 50 = 150 fish. If a third of them get spoiled 1 / 3 * 150 = 50 fish get spoiled. The remaining number of fish is now 150 - 50 = 100. He then gets 200 more to make 100 + 200 = 300 fish.. The answer is: 300.

John buys 2 packs of gum and 3 candy bars. Each stick of gum cost half as much as the candy bar. If the candy bar cost $1.5 each, how much did he pay in total?
Let's think: The gum cost $1.5 / 2 = $.75 per pack. So he pays $.75 * 2 = $1.5 for the gum. He pays $1.5 * 3 = $4.5 for the candy bars. So in total, he pays $1.5 + $4.5 = $6.. The answer is: 6.

The pet shop grooms dogs. It takes 30 minutes to groom a poodle. It takes half as much time to groom a terrier as it takes to groom a poodle. They do not groom cats. If the pet shop grooms 3 poodles and 8 terriers, what is the total length of time it will take, in minutes?

At a rate of 30 minutes per poodle, 3 poodles will take 3 * 30 = 90 minutes. If it takes half as much time to groom a terrier as it takes to groom a poodle, it takes 30 / 2 = 15 minutes per terrier. At a rate of 15 minutes per terrier, 8 terriers will take 120 minutes. Thus, in total, it will take the pet shop 90 + 120 = 210 minutes to groom 3 poodles and 8 terriers.. The answer is: 210.
