Liam wants to buy a car. he has $100. the car that he wants costs $120,000. his parents is willing to give him $1,300. how long will it take him to get enough money to buy the car?

Suspecting that his parents are going to give him $1,300 continually you would solve like this

$120,000-$100= $19,900
$19,900/$1,300= 92.23
92.23 is the amount of $1,300 donations it would take from his parents, so if he was getting $1,300 month it would take 92.23 months
