Answer:

B: 5x+30>7

Explanation:

he situation can be modeled by a linear inequality of the form px + q > r, where p is the number of miles Tammy runs per day, q is the number of miles Tammy has already run, and r is the total number of miles she needs to run more than.

In this case, p = 5, q = 30, and r = 70.

Therefore, the following inequality can be used to solve for x, the number of days Tammy still needs to run to reach her fitness goals.

5x + 30 > 70
