a plumer charged x dollars per hour for a 3-hour job plus $125 for parts. the total charge for the service call was $305. which equation can be used to determine how much the plumber charged per hour

Answer 1

$60.00 /h

Explanation:

y = mx + b

y, is the total charge

m, is the amount of money charged/h

x, is the number of hours

b, is the fixed rate

305 =m3 + 125

305-125 = m3

180/3 = m3/3

[60 = m]
