Eric · Answer 2

She needs to make 76 $100 purchases.

Step-by-step explanation:

Let's represent this with an equation. We know she already has 6000 miles.

6000 +

She earns 250 per 100 spent dollars. Let's represent the amount of $100-purchases with x.

6000 + 250x

Her ultimate goal is to get 25,000 miles.

6000 + 250x = 25000

Now all we have to do is solve!

250x = 19000

x = 19000/250 = 76

She needs to make 76 $100 purchases.
