Answer:
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.
