Me i really need i need it today show work

answer:

8 packages

step-by-step explanation:

first you subtract the one-time shipping fee from total

109.10 - 5.50 = 103.6

next you divide the 103.6 by 12.95 to find the number of packages

103.6 / 12.95 = 8

algebraic equation: 12.95x + 5.50 = 109.10

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

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
