[Question]Kara mixes cups of sugar and water in the ratio of 1:2 to make one liter of lemonade. Calculate the total number of cups of sugar used if she used 84 cups to make lemonade.
[Answer]The total ratio for the cups of sugar and water needed to make lemonade is 1 + 2 = 3. In the 3 cups needed to make one liter of lemonade, the fraction representing the cups of sugar needed is 1 / 3. If she used 84 cups while making lemonade, she used 1 / 3 * 84 = 28 cups of sugar. The answer is 28.
Q: Amber goes to the store and buys 10 rolls of toilet paper, 7 rolls of paper towels, and 3 boxes of tissues. One roll of toilet paper costs $1.50. One roll of paper towels costs $2. If the total cost of all the items is $35, how much does one box of tissues cost?
A: The total cost of toilet paper is 10 * $1.5 = $15. The total cost of paper towels is 7 * $2 = $14. The total cost of tissues is $35 - $15 - $14 = $6. The cost of one box of tissues is $6 / 3 = $2. The answer is 2.
