    T = 21.79x + 3.99x + 6.89x where t is the total cost and x is the number of brushes/rollers/paint cans you buy. You don't need a different variable for each item because you buy the same amount of each.

    If you purchase of each item, then you'll pay 3.99N for brushes,

    21.79N for cans of paint, and 6.89N for rollers.

    3.99N + 21.79N + 6.89N

    = N (3.99 + 21.79 + 6.89)

    = 32.67 N.
