$

10.75

Any additional topping adds:

+

$

1.25

So a cheese pizza with

1

additional topping is:

$

10.75

+

$

1.25

=

$

12.00

A cheese pizza with

2

additional toppings is:

$

10.75

+

If you pay attention to the pattern you can see that, for any number of toppings, say

x

toppings, the price is going to be:

$

10.25

+

x

*

$

1.25

We are told the final cost is

$

17.00

. That is

$

10.25

+

x

*

$

1.25

=

$

17.00

Subtract

$

10.25

from both sides

$

10.25

-

$

10.25

+

x

*

$

1.25

=

$

17.00

-

$

10.25

x

*

$

1.25

=

$

6.25

Divide both sides by

$

1.25

x

*

$

1.25

$

1.25

=
