Answer:
Plumber A
Step-by-step explanation:
Given the following :
Hours ___repair cost
________A ____B____C_____D
1 ______$35___55___50____50
2 _____ $65__ $75__ $75__ $60
3 _____ $95__ $95 _$100 ___$70
Charge plan:
Flat fee(x) + hourly rate(y)
For 1 hour:
Plumber A:
x + y = 35 ; x = 35 - y
x + 2y = 65 ;
35 - y + 2y = 65
y = 65 - 35 = $30 hourly
Plumber B:
x + y = 55 ; x = 55 - y
x + 2y = 75 ;
55 - y + 2y = 65
y = 65 - 55 = $10 hourly
Plumber C:
x + y = 50 ; x = 50 - y
x + 2y = 75 ;
50 - y + 2y = 65
y = 65 - 50 = $15 hourly
Plumber D:
x + y = 50 ; x = 50 - y
x + 2y = 60 ;
50 - y + 2y = 60
y = 65 - 50 = 10 hourly
Hence, Plumber A charges the highest hourly rate at $30 per hour
