Last year, she spent an average of $216 per month on utilities, but she anticipates a 5% increase in the annual cost of utilities.

Explanation:

----------------------------

AOPS does not accept 226.8 dollars as an answer as I have tried. The solution that the system accepts is 226.80 dollars.

Answer 2

$226.8

Explanation:

Given that the previous cost is

$216 per month

she expects an increase of 5% of the previous cost

therefore 5% of $216 is given as

=(5/100)*216

=0.05*216=10.8

Therefore she should be expected to pay extra $10.8 and the previous amount

hence the expected utilities each month is

=10.8+216=

=$226.8
