a pizza place charges $15 for a pepperoni pizza and $12 for a cheese pizza. the goal is to sell $540 in pizza for the day. The s

Ede4ka [16]

The pizza place should sell 45 cheese pizza in order to reach daily goal.

Step-by-step explanation:

Let, x=pepperoni pizzas and y= cheese pizzas.

And 15x+12y=540

If pizza place runs out of pepperoni pizza, then x=0 we need to find how many cheese pizza (y) must be sold to achieve the goal.

Putting x=0 and finding y,

$15x+12y=540\\15(0)+12y=540\\12y=540\\y=\frac{540}{12} \\y=45$

So, The pizza place should sell 45 cheese pizza in order to reach daily goal.
