Question

A) 25
B) 5
C) 45
D) 15

Answer 1

After Mary posted 13 fliers last week and 34 fliers this week from the original 72, she has 25 fliers remaining to post around town.

Step-by-step explanation:

To determine how many fliers Mary has left to post, we will subtract the number of fliers she posted from the total number she started with. Mary had 72 fliers to post around town. Last week, she posted 13 of them, and this week, she posted 34 of the remaining fliers.

We can set up the following subtraction to find the solution:

1. Subtract the fliers posted last week from the total: 72 - 13 = 59 fliers remaining after last week.
2. Subtract the fliers posted this week from the remaining fliers: 59 - 34 = 25 fliers remaining.

Therefore, Mary has 25 fliers left that she has still not posted. The correct answer is A) 25.
