Answer 1

Answer:

At 8 games, the girls will have the same ammount of money remaining.

Step-by-step explanation:

So we want to know at what time does these equations become the same. We simply write a equality like this:

$15-.75x=$13-.50x

We want to move the x over to the other side of the equation by simply doing this:

-.75x+.50x=13-15 --> Remember that this is a positive .50 because we did the opposite

Simplify

-.25x=-2 --> Remember that two negatives make a positive

x=8
