Victoria has 12 photo albums to make gifts for her family. Each photo album will need $0.30 of buttins and $1 of ribbon. She estimates she will spend $15. Did she overestimate or underestimate?

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

i think it would be c
