Step 1: Find the total plates of chicken rice sold.
45 + 38 + 52 + 44 + 61
= 83 + 52 + 44 + 61
= 135 + 44 + 61
= 179 + 61
= 240 plates
Step 2: Find the total plates of noodles sold.
32 + 41 + 28 + 35 + 22
= 73 + 28 + 35 + 22
= 101 + 35 + 22
= 136 + 22
= 158 plates
Step 3: Find the difference.
240 − 158 = 82 plates
