Rich bought 5 cupcakes and one pie. He know his total bill and know the pie was 6.88, but he wants to find the price if the cupcakes. How can he determine the price of each cupcake?

if there is no tax he can subtract 6.88 from the total bill and then divide the answer by 5 or use the following equation:

where t = total bill and c = cupcake

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

umm you say your want to . but you do know that this is the mathematics.
