Question

Mr. Johnson sells erasers for $3 each. He sold 96 erasers last week and he sold 204 erasers this week. About how much more money did he make this week?

Answer 1

96*3=288
204*3=612
612-288=324

He made $324 more

Answer 2

$324

Explanation:

In order to calculate how much more money he did, first we need to calculate the earning of each week. Then, subtract the this week's earning from last week's earning.

Last week's earning: 96 * 3 = 288

This week's earning: 204 * 612

The difference is → 612 - 288 = 324
