4 Steps in Solving Multi-Step Routine Problems

Step 1: Understand

So they baked 5 Sapin-Sapin with 20 slices each and shared it to their 36 neighbors with 2 slices per person. We are to find the number of people who can still eat Sapin-Sapin with 2 slices each.

Step 2: Plan

Multiply 5 by 20 and subtract the product of 36 and 2 to it. Then divide it's difference by 2 to get the answer.

Step 3: Solve

(5 × 20) - (36 × 2) = 100 - 72 = 28

28 ÷ 2 = 14

Step 4: Check

36 + 14 = 50 × 2 = 100

So, there are 14 more people who can eat the Sapin-Sapin.

Hope it helps :)
