Question

The table below shows the ticket rates for whale watching trips offered by Ocean Tours:
Age Ticket Price
Under 3 years free
3 to 12 years $36
Over 12 years $48

On a certain day, the company took 92 people on whale watching trips. There were 40 children aged 12 and under, of which some children were under 3 years. If x represents the number of children under 3 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? (4 points)

Answer 1

Possible Answers:
(92 - x)36 + (92 - 40) ⋅ 48 = C
(40 + x)36 + (92 - (40 + x)) ⋅ 48 = C
(92 + x)36 + (92 - (40 + x)) ⋅ 48 = C
(40 - x)36 + (92 - 40) ⋅ 48 = C

Answer 2

(40-x)(36) + (92 - 40) * 48 = C

There were 92 people total, 40 of which were under 12, leaving the (92-40) people over 12. Each ticket for them cost 48 dollars, so the revenue for people over 12 is (92-40)(48)
There's an unknown number of people that's under 3.

The kids that are under 3 do not generate revenue, so they're not a part of the cost. Essentially, they are x * 0 = 0 anyways

Answer 3

Okay :) Thanks!
