Problem
(1) The school is planning a field trip to the science center. Tickets are originally \( \$ 28 \), but school groups receive an \( \$ 8 \) discount on each ticket that is purchased. The expression \( t(28-8) \) represents the total cost for \( t \) tickets. (1) What does the quantity \( 28-8 \) represent? Order of Operations the discounted price of each ticket 1 Evaluate inside parentheses. (1) Mrs. Price purchases 24 tickets for the students in her class. Evaluate the expression for \( t=24 \). \[ \begin{aligned} t(28-8) & =24(28-8) \\ & =24(\square) \end{aligned} \]
Solution
Step 1 ：t(28-8) = t(20)
Step 2 ：24(20) = 480
