Please help! I need this fast. A music store sells regular CDs for $8.50. On average, the store sells 90 CDs every day. For each 50-cent increase in the price of regular CDs, the sales of CDs will go down by 5. What should the CD price be to get the most income from CD sales?

answer: 3.26019516

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

here's a poem i finished a while ago. i hope you like it and that it inspires you.
