4. A food delivery service charges a $100 membership fee to join, and also charges $5 for each delivery. Find the linear equation that models the cost based on number of deliveries. At the total cost of $200, how many deliveries will have been made?

200-100=5(x)

Step-by-step explanation:

If the total cost is 200 dollars and we spent 100 on the fee, we have 100 dolars for deliveries.

If each delivery is 5 dollars, then the amount of money spent on deliveries is x(unknown) dollars then we have 200 - 100 = 5 x   <--unknown

                                     total money^        ^fee   ^each deliv
