    A. If a camera is rented for 1 or 2 days, it would be logical to rent it from Murphy’s.

    B. If a camera is needed for more than 3 days, it would make sense to rent it from Allied rental.

    C. Yes, if a camera is rented for 3 days both rentals charge the same money.

    C. If you were need a camera for 3 days, you would have to pay $135 for both stores.

    Step-by-step explanation:

    Step 1; Murphy’s camera costs $30 to rent and an additional $35 for each day of rental. So the equations are

    y = $30 + (x × $35), where y is total cost and x is the number of days rented.

    So for x = 1, y = $30 + (1 × $35) = $30 + $35 = $65

    So for x = 2, y = $30 + (2 × $35) = $30 + $70 = $100

    So for x = 3, y = $30 + (3 × $35) = $30 + $105 = $135

    So for x = 4, y = $30 + (4 × $35) = $30 + $140 = $170

    So for x = 5, y = $30 + (5 × $35) = $30 + $175 = $ 205.

    Step 2; Allied rental costs $45 to rent and a $30 for each day of rental. So the equations are as follows

    y = $45 + (x × $30), where y is total cost and x is the days rented

    So for x = 1, $45 + (1 × $30) = $45 + $30 = $75

    So for x = 2, $45 + (2 × $30) = $45 + $60 = $105

    So for x = 3, $45 + (3 × $30) = $45 + $90 = $135

    So for x = 4, $45 + (4 × $30) = $45 + $120 = $165

    So for x = 5, $45 + (5 × $30) = $45 + $150 = $195

    Step 3; Comparing both prices over 5 days. Murphy’s is cheaper for until 2 days. On day 3 both the rentals cost the same but after day 4, allied rentals is the better option.
