Question

A one-day pass to an amusement park costs $40. A round-trip bus ticket to the park costs $5. Write two equivalent expressions to find the total cost of a one-day pass and a bus ticket for 15 students.

Answer 1

• (40 + 5)*15
• 40*15 + 5*15

Explanation:

Each student pays $40 and $5 and there are 15 students.

The total cost can be expressed in two ways as:

• 1) (40 + 5)*15 = 45*15 = 675

• 2) 40*15 + 5*15 = 600 + 75 = 675
