Answer:
$148.00
Step-by-step explanation:
y is the total amount of money the electrician will charge.
x is the hours they work
$68 is the materials cost
y = $68 + 40(x)
It should all equal y since y is the total cost for the electricians service. You plug in 2 in place of x since it took them 2 hours.
y = 68 + 40(2)
y = 68 + 80
y = 148
