Step-by-step explanation:
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.
