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?

Answer 1

Here are the answers/choices:

(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

I believe it is D.

Answer 3

And your explanation?

Answer 4

Thanks, I'll go with that I hope it's right . . .

Answer 5

(40-x)36 represents the total amount collected from 3-12 yrs old since x represents the no of children under 3. (92-40)48 are the money collected from children over 12 yrs since there are only 40 children 12 and under. Hope you get it. :))
