Question

The table below shows the ticket rates for whale watching trips offered by Orca Magic Tours.

Age Ticket Price
Under three years free
Three to twelve years $32
Over twelve years $44

Answer 1

On a certain day, the company took 82 people on whale watching trips. There were 54 children aged twelve and under, of which some children were under three years. If x represents the number of children under three years, which equation can be used to find the value of x, where C represents the total amount of money collected from tickets that day?

(54 + x)32 + (82 - (54 + x)) ∙ 44 = C
(54 - x)32 + (82 - 54) ∙ 44 = C
(82 + x)32 + (82 - (54 + x)) ∙ 44 = C
(82 - x)32 + (82 - 54) ∙ 44 = C
