Question

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

Answer 1

Answer:

$112.50

Step-by-step 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

$\frac{2}{25} = \frac{9}{x}$

$\frac{25 \times 9}{2} = \frac{225}{2}$

x=112.5

check:
$\frac{2}{x} = \frac{9}{112.5}$


$\frac{2 \times 112.5}{9} = \frac{225}{9} = 25$
