Tammy must run more than 74 miles total to reach her fitness goals. She has already run 34 miles and runs 5 miles per day. Which of the following inequalities could be used to solve for x, the number of days Tammy still needs to run to reach her fitness goals?
Let x represent the number of days Tammy still needs to run. The total number of miles she still needs to run can be represented as:
Total miles to run = 74 - 34 = 40
Tammy runs 5 miles per day, so the total miles she will run in x days is:
5x
Therefore, the inequality that could be used to solve for x is:
5x ≥ 40
