2014 AMC 12A Problems/Problem 2

Suppose $x$ is the price of an adult ticket. The price of a child ticket would be $\frac{x}{2}$ .

$5x + 4(x/2) = 7x &= 24.50$ (Error compiling LaTeX. Unknown error_msg)

$x &= 3.50$ (Error compiling LaTeX. Unknown error_msg)

Plug in for 8 adult tickets and 6 child tickets.

$8x + 6(x/2) = 8(3.50) + 3(3.50) = 38.50$
