You can set up 2 equations for the two companies that sell pizza. Pizza A's will be:
y = 1.5x+10

And B's will be:
y = x+12.50

To find the number of toppings we will need to make the companies prices equal can be found by setting the equations equal to each other and solving for x, because x is the price per topping. So:
1.5x+10 = x+12.50
1.5x = x+2.50
0.5x = 2.50
x  =   \frac{2.5}{0.5}  = 5

So, the number of toppings you will need is 5 toppings to make their prices equal.
