Sunny earns $22.75 per week delivering newspapers. He worked as a delivery boy for 3 weeks. He also earned $32.75 last month doing chores around the house. He spent $14.25 of his total earnings to download music on his mobile device. Sunny put 1 over 5 of the remaining money in his savings account. Sunny used the following steps to find the total money he put in his savings account:

Step 1: [($22.75 + 3) + $32.75 − $14.25] ⋅ 1 over 5

Step 2: [$44.25] ⋅ 1 over 5
