Q: Penelope has 5 M&M candies for every 3 Starbursts candies. If she has 25 M&M candies, how many Starbursts candies does she have?
A: Let 5 M&M candies and 3 Starbursts candies be referred to as the unit amounts of each candy. 5 M&M candies make one unit so 25 makes 25 / 5 = 5 units of M&M candies. For every unit of 5 M&M candies, there is a corresponding unit of 3 Starbursts candies so for 5 units of M&M, she has 5 units of 3 Starbursts candies which is = 5 * 3 = 15 Starbursts candies. The answer is 15.
Question: Sally sold 20 cups of lemonade last week. She sold 30% more lemonade this week. How many cups of lemonade did she sell in total for both weeks?
Answer: If Sally sold 30% more lemonade this week, she sold 20 * 30 / 100 = 6 more cups this week. This week, Sally sold 20 + 6 = 26 cups of lemonade. In total for both weeks, Sally sold 20 + 26 = 46 cups of lemonade. The answer is 46.

Q: Alice wants 1000 folded paper cranes. She folds half by herself, and a friend folds a fifth of the remaining paper cranes for her. How many paper cranes does Alice still need to fold?
A: Alice folds 1000 * 0.5 = 500 paper cranes by herself. This leaves 1000 – 500 = 500 paper cranes left to fold. A friend folds a fifth of the remaining amount, so they have folded 500 / 5 = 100 paper cranes for her. This means there is a total of 1000 – 500 – 100 = 400 paper cranes left for Alice to fold. The answer is 400.
Question: Brad wanted to set up a lemonade stand to earn some money. Every gallon of lemonade would yield 16 glasses. He figured it would cost him $3.50 to make every gallon of lemonade. He made 2 gallons to sell and decided he would sell each glass for $1.00 He drank 5 glasses while sitting in his stand. He sold all but 6 glasses of lemonade. How much net profit did Brad earn?
Answer: He made 2 gallons and each gallon had 16 glasses so 2 * 16 = 32 glasses. He drank 5 glasses and had 6 left over which means he would not earn money on 5 + 6 = 11 glasses. The total revenue would come from 32 - 11 = 21 glasses. Each gallon cost $3.50 to make so the total cost was 2 * 3.50 = $7.00. He sold 21 glasses at $1.00 per glass for a total of 1 * 21 = $21.00. When you take his earnings of $21.00 and subtract the cost of $7.00 his total net profit was 21 - 7 = $14.00. The answer is 14.
Q: Dave weighs 175 pounds and can bench press three times his body weight. Craig can only bench press 20% of the amount Dave can. Mark is new and can bench press 50 pounds less than Craig. How much can Mark bench press?
A:
Dave weighs 175 pounds and can bench press three times his body weight, so he can bench press 175 * 3 = 525 pounds. Craig can only bench press 20% of Dave's 525 pounds, so Craig can bench press .20 * 525 = 105 pounds. Craig bench presses 105 pounds and Mark does 50 pounds less than Craig, so Mark can only press 105 - 50 = 55 pounds. The answer is 55.
