Answer: t = 5m + 100
Step-by-step explanation:
We will use the given information to create an equation.
   "t, the total amount that Jamal has paid the store" âžœ t = Â
   "he will pay $50 each month" ➜ 50m (slope)
   "He made an initial payment of $100" ➜ + 100 (y-intercept)
This gives us the following equation:
   t = 5m + 100
