Question

Peyton is a teacher and takes home 87 papers to grade over the weekend. She can grade at a rate of 7 papers per hour. How many papers would Peyton have remaining to grade after working for 12 hours

Answer 1

Peyton would have 3 papers remaining to grade after working for 12 hours.

Explanation:

1. Make an equation to represent this problem.

87 - (7 * 12) = r

(r represents how many papers are remaining after 12 hours.)

2. Solve 7 * 12.

87 - (84) = r

3. Subtract.

3 = r
