Question

A bicycle store costs $2400 per month to operate. The store pays an average of $60 per bicycle. The average selling price of each bicycle is $120. How many bicycles must the store sell each month to break even?

Answer 1

$2400 +$60b = $120b
$2400 -$60b-$60b =$120b-$60b
$2400 = $60b
$2400/$60 = $60b/$60
b= 40

Check
$2400 + $60b = $120b
$2400 + $60(40) = $120(40)
$2400 + $2400 = $4800
$4800 = $4800

They must sell 40 bikes to break even.

Answer 2

You need to divide 2400/120 and see what you get. te answer is 20
