Answer:
180
Step-by-step explanation:
let x = total units of electricity after 250 units
the total units of electricity consumed can be determined using the formula below
80 + 7.3x = 1248
7.3x = 1248 - 80
7.3x = 1168
divide both sides of the equation by 7.3
x = 1168 / 7.3
x = 160
total electricity consumed = 160 + 20 = 180
160
Your answer would be D. They're all the same, Hope I helped!
