Please answer the following question by reasoning step-by-step.
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?

2
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.

.

Thus, the answer is 2
