Question

Which strategy best explains how to solve this problem?

Rebecca bought a meal and two snacks for lunch each day. The meal cost $5.50 and the snacks cost $0.75 each.



What is the total amount of money Rebecca spent after 12 days?

Answer 1

A.

Make a table.

Write the numbers 1 to 12 in the top row of the table (the number of days). In the first box on the second row, write $7. This is how much Rebecca spends in 1 day. In each of the next boxes in the second row, write the amount Rebecca spends by adding $7 to the previous amount. The answer in box 12 is the total amount Rebecca spent after 12 days.








B.

Work backward.

Start with the price of the two snacks ($1.50). Add the cost of the meal and then divide by 12.








C.

Guess and test.

Guess that Rebecca spent $95. Multiply $0.75 by 2. Then add that answer to $5.50. Divide this number by 95. If the answer is not 12, then revise your guess, and test your answer again.
