Question

A grocery delivery service has 22 members. Each member pays monthly dues of $12.80

Answer 1

The answer is C. 166.40

22 - 9 = 13 ( members who paid on the third)
13 x $12.80 = $166.40

Answer 2

Answer:

C

Step-by-step explanation:

If 9 members paid on the first day, this means they did not pay on the third day

The remaining people (everyone but the 9) paid on the third day

Therefore we must subtract to find out how many members paid on the third day

22 - 9 = 13

Each of the 13 members paid $12.80 which means we must multiply

13 × 12.80 = 166.40

In total, the grocery store collected $166.40 on the third day of the month
