Question

A restaurant sells pizzas according to the formula y=8.50+0.45(x-3), where x represents the total number of toppings. You can spend no more than $10 on a pizza. What is the range of the this situation?

Answer 1

the formula is

$y=8.50+0.45\left(x-3\right)$

For $10,

$\begin{gathered} 10=8.5+0.45(x-3) \\ 10-8.5=0.45x-1.35 \\ 1.5+1.35=.45x \\ \frac{2.85}{0.45}=x \\ x=6.3 \end{gathered}$

So when, x=6.3, y=$10,
