Question

Write an equation to show the total cost, y, for a day at the museum of natural history for x people. a) y = 15x + 5 b) y = 20x c) y = 25x - 5 d) y = 30x

Answer 1

See below.

Explanation:

The charge for a museum ticket is missing. It is also unclear if there is a service charge. The expressions offer 4 different possibilities:

Charge/person($/person) Service Charge($)

a) y = 15x + 5 15 5

b) y = 20x 20 0

c) y = 25x - 5 25 - 5 (!)

d) y = 30x 0 0

Match the values with the information provided. c) is unlikely due to the -$5service fee. I don't know of any museum that will pay you $5 to buy tickets, but its not a bad idea.
