Three families each buy the same number of $10 tickets per person to the zoo. Each family also pays $2 for parking. The total cost is $126. Write an equation that can be used to find n, the number of people in a family.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
