Answer 1

Answer:

$35 + 4x > 67$

To reach her fitness goal, she needs to run for more than 8 days.

Step-by-step explanation:

She has already run 35 miles and runs 4 miles per day:

This means that after x days, the distance she will have run is:

$D(x) = 35 + 4x$

Tammy must run more than 67 miles total to reach her fitness goals.

This means that:

$D(x) > 67$

$35 + 4x > 67$

The inequality is:

$35 + 4x > 67$

Solution:

$4x > 32$

$x > \frac{32}{4}$

$x > 8$

To reach her fitness goal, she needs to run for more than 8 days.
