Question

Mick O'Meara budgeted $315 per month for electricity and $238 per month for gas. His expenses for a twelve-month period were $3,950 for electricity and $3,055 for gas.How much less did he budget annually for the two expenses than he needed?$339$344$357$369None of these choices are correct.

Answer 1

In order to know how much he budgeted annually for each expense, we need to multiply each month budget by 12:

annual budget for electricity: 12 * 315 = 3780

annual budget for gas: 12 * 238 = 2856

So, the total annual budget was:

3780 + 2856 = 6636

On the other hand, his real expenses for that year were:

3950 + 3055 = 7005

Then, to find how much less he budget than he needed, we can find the difference between those two values:

7005 - 6636 = 369

Therefore, the last option is correct.
