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
1st option
You can get the number of adults by subtracting 103 by the number of children (64). Take that number and apply the adult rate. From there you have the variable x that you are trying to determine for kids under 3.
