Group of answer choices

Answer 1

Answer:

F(x) = 50 + 26x ( here x is the number of hours worked)

Step-by-step explanation:

flat fee to visit $50

plus an hourly charge, let it be y

for four hours he had charged $154

mathematically 50+4y = 154

4y = 154-50

4y = 104

y = 104/4 = 26

so he charge $26 as an hourly charge

function that will calculate the cost of repairmen will be given as

F(x) = 50 + 26x ( here x is the number of hours worked)
