The hotel room tax in Junction City is calculated using the function T(x) =0.06x + 4.5, where x = the cost in dollars of the room and T(x) = the tax in dollars. What is the tax on a room that costs $120?

Respuesta :

Since the tax on the room is given by the function:

T(x)=0.06x+45

And x(cost in dollars of the room) is given= $120, you just have to subtitue x=120 on the function

T(120)=0.06(120)+4.5

T(120)=7.2+4.5

T(120)=11.7

So, the tax in dollars would be $11.7
