Exercise 5 Page 3

We do not need to find the cost, just write the math expression we would need to compute it.

Example Solution: 5(9) + 5(3) + 5(6)

We need to write an expression about the cost of the movies, given that each friend pays $9 for a ticket, $3 for a drink, and $6 for popcorn. Let's work it out as if we are purchasing each item for 5 people at a time.
Item Price per Person Price for 5 People
Tickets $9 5 * 9
Drink $3 5 * 3
Popcorn $6 5 * 6
Total Cost 5(9) + 5(3) + 5(6)

Alternative Solution

Pricing Per Person

Alternatively, we can start by working out how much it cost for one person. ticket + drink + popcorn = 9 + 3 + 6 Now, we would multiply that sum by 5. Total Cost= 5(9 + 3 + 6)
