Answer:
Initial value for store A = 300$
Initial value for store B = 200$
Explanation: The initial value is the value of y, when x is 0. Here the x axis will represent the month, while y would represent the amount the buyer owes on that month. For store A, at month 0, the buyer owes 300$. For store B, there is an instant payment of 100$, leaving the buyer to owe 200$ from the start of the deal, hence the reason for my initial values above.
Step-by-step explanation:
Rate of Change for store A = 300 - 250 = 50
Rate of change for Store B = 50
The rate of change in this case is the same, as the rate of change is defined as how fast the output change in relation to the input. In both cases, they are required to pay 50$ each month.
