If the discount rate is 20%, just substitute 0.2 for d in your equation
T = n [6+6(.05)-0.2(6+6(.05))]
Note that the n multiples all terms. I used brackets to clarify that. I think your original equation omitted an important pair of parentheses.
A student ticket to a flower show costs $6.00 plus a 5% handling fee. The local schools receive a special group discount. A scholl can determine the total cost of tickets by using the formula below.
T = Total cost
N = Nmber of tickets purchased
D = Discount rate
T = n(6+6(.05))-d(6+6(.05))
If the discount rate is 20%, what equation can be used to determine the total cost of the tickets.
