Answer:
135 miles
Step-by-step explanation:
So first we have to find the difference of 83 and 100. So 100-83=27. So for miles, she can spend 27 dollars. Now, since per mile it costs 20 cents or 1/5 of a dollar, every time she drives 5 miles she'll have to pay one more dollar. So One dollar = 5 miles. Then we do the total amount of money she can spend on miles (27) and multiply that by the amount of miles per dollar (5) and we get 135 miles. So she can drive 135 miles.
