Angelica started with half a tank of gas in her car, and she used of that. Write an equation in the text box. Solve to show how much of a full tank she used.

Ans

Step-by-step explanation:

Let one full tank = x

Then by the given statement, Angelica started with x/2

Suppose she used half of that, then,

x/4. So that x/4 - x/2 = x/4

This implies that she travelled half the distance she would have, using a full tank.

Suppose her destination requires 3 full tanks, then she would stop three times for a refill.
