Janice jogged 2.35 miles yesterday and 2.45 miles today. If she wants to run a total of 8 miles by tomorrow, how many more miles does Janice need to jog?

there is a number line with 3.0 on one end and 4.0 on the other

3.2 miles

Step-by-step explanation:

The number line tells you that the final answer should be between 3 and 4.

To solve this problem you would add up the number of miles Janice ran yesterday and today and subtract this amount from 8.

2.35 + 2.45 = 4.8

Subtract 4.8 from 8.

8 - 4.8 = 3.2

Janet has 3.2 more miles to jog to reach her goal of 8 miles. So yes, the answer should be correct since the number is between 3.0 and 4.0.
