Question: Tony's dad is very strict about the washing machine and family members are only allowed to wash 50 total ounces of clothing at a time. Tony doesn't want to break the rules, so he weighs his clothes and finds that a pair of socks weighs 2 ounces, underwear weighs 4 ounces, a shirt weighs 5 ounces, shorts weigh 8 ounces, and pants weigh 10 ounces. Tony is washing a pair of pants, 2 shirts, a pair of shorts, and 3 pairs of socks. How many more pairs of underwear can he add to the wash and not break the rule?
Answer: He is washing 10 ounces of shirts because 2 x 5 = 10. He is washing 6 ounces of socks because 3 x 2 = 6. He is already washing 34 ounces of clothes because 10 + 10 + 8 + 6 = 34. He can wash 16 more ounces because 50 - 34 = 16. He can wash 4 pairs of underwear because 16 / 4 = 4. The answer is 4.

Question: GiGi took out a big bowl of mushrooms from the refrigerator. She cut each mushroom into 4 pieces. Her twins, Kenny and Karla sprinkled mushrooms on their pizzas and baked them in the oven. Kenny grabbed a handful and sprinkled 38 mushroom pieces on his pizza. Karla scooped them up with both hands and sprinkled 42 mushroom pieces on her pizza. On the cutting board, were 8 pieces of mushrooms remaining. How many mushrooms did GiGi cut up at the beginning?
Answer: Kenny used 38 / 4 = 9.5 mushrooms on his pizza. Karla used 42 / 4 = 10.5 mushrooms on her pizza. Together, the twins used 9.5 + 10.5 = 20 mushrooms. There are 8 / 4 = 2 mushrooms left on the cutting board. GiGi cut up 20 + 2 = 22 mushrooms at the beginning. The answer is 22.

Question: 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?
Answer: He drinks 15 bottles every month and there are 12 months in 1 year so that's 15 * 12 = 180 bottles. He earns $0.10 on every bottle that he recycles so that's .10 * 180 = $18.00. He has $18.00 and each bottle costs $3.00 so he can buy 18 / 3 = 6 bottles. The answer is 6.

Question: Alice has 20 quarters. She wants to exchange them for nickels and so she goes to the bank. After getting back from the bank, she discovers that 20% of the nickels are iron nickels worth $3 each. What is the total value of her money now?
Answer:
A quarter is worth five nickels because .25 / .05 = 5. She gets 100 nickels from the bank because 20 x 5 = 100. 20 of the nickels are iron nickels because 100 x .20 = 20. 80 of the nickels are regular because 100 - 20 = 80. The iron nickels are worth $60 because 20 x 3 = 60. The regular nickels are worth $4 because 80 x .05 = 4. Her money is now worth $64 because 60 + 4 = 64. The answer is 64.
