Question

Can someone please help me with number 13.

Answer 1

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 = (2.5)/(0.5) = 5`

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