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

Answer 1

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?
(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

There are 10 boys and girls in a class.
x are boys.
How many are girls?

There are 40 children.
x are under 3.
How many are over 3?
Answer: 40 - x

Read the above and concentrate on the third question.

Answer 22

Ok. I'll finish it.
There are 92 people.
92 - 40 are adults who pay $48 per person
40 - x are children over 3 who pay $36
x are children who pay nothing

The cost is:

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