to earn money for college, susan is making and selling earrings. her weekly costs for advertising and phone calls are $36, and each pair of earrings costs $1.50 to produce.
Total cost = 36+1.5x to produce "x" earrings.
======================================================
if susan sells the earrings at $6 per pair, how many pairs must she sell per week to break even?
Revenue = 6x for selling "x" earrings.
-------
Equation to determine the break even # of earrings.
36+1.5x = 6x
4.5x = 36
x = 8 earrings.
