Your working in a furniture store and your base salary is $1,000 per month plus 6.5% of all sales over
$3,000. Your monthly family expenses are $1,800 per month. How much in sales must you generate each month to cover your family expenses?

s = amount of sales you must generate to cover expenses

$1,800 = $1,000 + 6.5%(s - 3000)
$1,800 - $1,000 = 6.5%s - 6.5%(3000)
$800 = .065s - .065($3,000)
$800 = .065s - $195
$800 + $195 = .065s
$995 = .065s
$995 ÷ .065 = s
$15,307.70 = s
