(a)

Answer to Problem 43PPS
The algebraic expression is
Explanation of Solution
Given:
Calculation:
Cost of admission to the center per person = $0
Cost of visiting planetarium per person = 4.50
Cost of watching a 3-D movie per person = 7.75
Algebraic expression to find total cost for five people to get into the center.
Hence it is the solution.
Conclusion:
The algebraic expression is
(b)
