Question 290325
John has $4,800
He needs $12,000
He is saving $500 per month.<br>
let's let "m" represent the number of months he must save.<br>
{{{ 500m + 4800 = 12000 }}}<br>
{{{ 500m + highlight(4800) = 12000 - highlight(4800) }}} Subtract 4800 from each side<br>
{{{ 500m =  7200 }}} next, divide each side by 500<br>
{{{ 500m /highlight(500) =  7200 /highlight(500) }}}<br>
{{{ m = 14.4 }}} months, so after 15 months he will have $12,000 + $300 extra
and bob's your uncle!
