Question

The table below shows the ticket rates for whale watching trips offered by Beluga Fun Tours: Age Ticket Price Under 3 years free 3 to 12 years $34 Over 12 years $45 On a certain day, the company took 103 people on whale watching trips. There were 64 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? (64 − x)34 + (103 − 64) ⋅ 45 = C (103 + x)34 + (103 −(64 + x)) ⋅ 45 = C (103 − x)34 + (103 − 64) ⋅ 45 = C (64 + x)34 + (103 −(64 + x)) ⋅ 45 = C

Answer 1

We have the following data:
 Under 3 years = 0 $
 3 to 12 years = $ 34
 Over 12 years = $ 45
 103 people
 There were 64 children aged 12 and under, of which some children were under 3 years
 If x represents the number of children under 3 years
 We have then that the equation is
 34 * (64-x) + 45 (103-64) = C
 answer
 C = 34 * (64-x) + 45 (103-64)
