Raul works at a movie theatre. The function f(x) represents the amount of money in dollars Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. f(x) = 3x2 + 16

g(x) = the square root of five times x cubed
Find f(g(x)).

f of g of x equals the square root of the quantity 15 times x to the fifth power plus 16 dollars over hour
f of g of x equals the square root of the quantity 15 times x to the fifth power plus 16 dollars over hour
f(g(x)) = 15x3 + 16 dollars over hour
f(g(x)) = 15x3 + 16 tickets over hour
