Well, first thing's first: find the area.
The formula for area is L*W
L=9 ft
W=6 ft
9*6=54 sq ft

<span>1)Consumption: 875 kWh / month
2) New rate:
- 7.5 cents / kWh for the first 600 kWh
- 13.0 cents / kWh the next 600 kWh
3) Calculation:
600 kWh * 7.5 cents/ kWh + (875 kWh - 600 kWh) * 13.0 cents / kWh.
4500 cents + 3575 cents = 8075 cents = $ 80.75, which rounded to the nearest dolar is $ 81.
Answer: option d. $81.

Remark
This is an excellent question. Estimation is a powerful skill to have. People should always shop using estimates. Try it to see what happens.
x = 11.7 which rounds up to which we will call x1 and that is 12
y = 6.03 which round down to 6 which we will call y1 and that is 6
Now x - y = 5.67
If you do the rounded subtraction x1 - y1 = 12 - 6 = 6
The estimate is not zero. D is not correct.
There is enough information E is not the answer.
B is wrong, her estimate is larger than x - y
C is wrong the two subtractions are not equal.
A is correct and always will be no matter what numbers are chosen
