Jason’s part-time job pays him $155 a week. if he has already saved
$375, what is the minimum number of weeks he needs to work in
order to have enough money to buy a dirt bike for $900?
(1) 8 (3) 3
(2) 9 (4) 4

So, he starts off with 375. He is paid 155 a week. The outcome will be 900.

You set it up like this-
375+155(x)=900
then, you subtract 375 from both sides.

155(x)=525
Then, you divide 155 from both sides.

x=3.3870967

This is where it gets a bit tricky. You CANNOT round down. This is because he would not have enough money if he stopped the week before. He would still need a little bit. Instead, you MUST round up. It will take a minimum of 4 weeks.

The answer is (4) 4
