12. [2.05] The table below shows the ticket rates for whale watching trips offered by Ocean Tours.
Age Ticket Price
Under three years free
Three to twelve years $36
Over twelve years $48
On a certain day, the company took 92 people on whale watching trips. There were 40 children aged twelve and under, of which some children were under three years. If x represents the number of children undr three 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

then it would be C = (5/9)*(F-32)
Divide both sides by (5/9)
Remember, when dividing fractions, switch the numerator and denominator, and then multiply by that fraction.
C*(9/5) = F-32.
Then add 32:
C*(9/5) + 32 = F
The 2nd part indicates that you plug a value for C to get the F value:
[(6)*9/5] + 32 = F
10.8 + 32 = F
42.8 = F
