Question

Marisa is keeping track of how many miles she runs. After her run on July 12, she had run a total of 7 miles. If she runs 3 miles each day after that, what is the total number of miles she will run after her run on july 18?

Answer 1

22 miles

Explanation:

July 12- 7

July 13- 3

July 14- 3

July 15- 3

July 16- 3

July 17- 3

July 18- 3

You can solve this by adding or doing a quick multiplication problem. Either method gets you the same answer I showed work for each below.

Adding: 7+3+3+3+3+3= 22

Multiplying: 7+5(3)= 7+15= 22
