The cost-volume formula for men's belts is y= 2.5x + 750, where x is the number of belts
produced per week. Determine the fixed cost and
the unit cost. Find the total costs when the weekly
production is
(a) 100 units (b) 300 units (c) 650 units

the answer is 62

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
