Question

If two large single-topping pizzas cost $25.00, how much will 9 pizzas cost?

Answer 1

$112.50

Explanation:

You take 25 + 25 +25 +25 = 100

that equals 8 pizzas

half of 25 is 12.5

so for one pizza it is $12.50

100 + 12.5 = 112.50

Answer 2

`(2)/(25) = (9)/(x)`


`(25 * 9)/(2) = (225)/(2)`

x=112.5

check:

`(2)/(x) = (9)/(112.5)`



`(2 * 112.5)/(9) = (225)/(9) = 25`
