Jolli Donuts charges Php 18 each for a special doughnut plus a fixed charge of Php 5 for the box which can hold as many as 24 donuts. How many doughnuts would be in a box priced at Php 221? Write
a rule that best describes the problem and draw its graph. In your graph, assume that only 1 to 24
doughnuts are sold.

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

the correct answer is d

hope this

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
