Cheese pizzas cost $7 and pepperoni pizzas cost $9. You order a total of 40 pizzas and the bill is $310. How many of each pizza

Anon25 [30]

Answer: cheese pizzas = 25 , Pepperoni pizzas = 15

Step-by-step explanation:

Let x = Number of cheese pizzas, y = Number of pepperoni pizzas.

As per given,

$x+y=40\ \ \ (i)\\\\ 7x+9y=310\ \ \ (ii)$

Multiply 7 on both sides of (i), we get

$7x+7y=280\ \ \ (iii)$

Eliminate (iii) from (ii), we get

$2y= 30\\\\\Rightarrow\ y=15$

Put value of y in (i) , $x+15=40\Rightarrow\ x= 40-15= 25$

Hence, cheese pizzas = 25 , Pepperoni pizzas = 15
