You can set up 2 equations for the two companies that sell pizza. Pizza A's will be:
[tex]y = 1.5x+10[/tex]
And B's will be:
[tex]y = x+12.50[/tex]
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:
[tex]1.5x+10 = x+12.50[/tex]
[tex]1.5x = x+2.50[/tex]
[tex]0.5x = 2.50[/tex]
[tex]x = \frac{2.5}{0.5} = 5[/tex]
So, the number of toppings you will need is 5 toppings to make their prices equal.
