Question

In the town of Brownville, the water company charges a flat rate of $5.56 for usage of less than or equal to 300 cubic feet and $1.74 for every 100 cubic feet used in excess of 300 cubic feet. If a resident consumes 800 cubic feet in one month, what will be the amount of the bill?
$15.24
$14.26
$12.76
$15.03
$12.33
