Tiffany is looking at a lake full of turtles. The turtles are 60% female and the rest are male. Of the males, 1 in 4 has stripes. Of the ones with stripes, 4 are babies, while 60% are adults How many turtles are in the lake? Give the rationale and then the answer.
Let's think step by step. Of the males with stripes, 40% are babies because 100 - 60 = 40. There are 10 males with stripes because 4 / .4 = 10. There are 40 males because 10 / (1 / 4) = 40. Males make up 40% of the pond's total, because 100 - 60 = 40. There are 100 turtles in total 40 / .4 = 100.. The answer is: 100.

Zoe goes to the store to buy soda and pizza for herself and her 5 family members. Each bottle of soda costs half a dollar and each slice of pizza costs $1. Before she leaves her house she takes just enough money to pay for her purchase. How much money did Zoe take? Give the rationale and then the answer.
Let's think step by step. Zoe is going to buy pizza and soda for 5 people + 1 person = 6 people. For 6 sodas, Zoe will pay 6 sodas * $0.5 / soda = $3. For 6 slices of pizza, she will pay 6 slices * $1 / slice = $6. Adding the price of the soda and pizza, Zoe paid $3 + $6 = $9.. The answer is: 9.

John hits 70% of his free throws. For every foul he gets 2 shots. He gets fouled 5 times a game. How many free throws does he get if he plays in 80% of the 20 games the team plays? Give the rationale and then the answer.
Let's think step by step. John plays in 20 * .8 = 16 games. That means he gets fouled 16 * 5 = 80 fouls. So he gets 80 * 2 = 160 foul shots. So he makes 160 * .7 = 112 free throws.. The answer is: 112.
