a plumber charges $50 to make a house call. He also charges $25.00 per hour for labor write an equation that you could to use the amount a plumber charges for a house call based on the number of hours of labor.

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

i hope this you!

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

ou would have 12 of each

you can't solve x because it is 2 linear equation and you only have one equation
