Mara Ross · Answer 1

Let us write an equations

1st pizza place costs 9.95 + x dollars, where x is the number of toppings

2nd pizza place 6.95 + 1.5 y dollars, where y is the number of toppings

We are interested when they are equal:

9.95 + x = 6.95 + 1.5y

3 = 1.5y - x

As the questions asks for the same ammount of toppings, x=y

3 = 1.5y - x this becames

3=0.5 x

x=6

Lets check

9.95+6=15.95

6.95+6*1.5=15.95

So the answers is 6
