The red bus company charges $150 plus $72 per hour to rent a bus. the blue bus company charges $240 plus 54 per hour. for what number of hours would the companies charge the same?

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

answer:

f(5/2) = 10/3
