Problem
4) 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? the discounted price of each ticket (1) Mrs. Price purchases 24 tickets for the students in her class. Evaluate the expression for \( t=24 \). \[ t(28-8)=\square(28-8) \]
Solution
Step 1 ：t(28-8)=24(28-8)
Step 2 ：t(20)=24(20)
Step 3 ：t=480
