Answer to Question #241468 in Financial Math for ariel

Question

Last month, my water meter had a reading of 0286 ccf. This month the reading was 0289 ccf. My water company charges $6.25 per ccf of water used. How much do I owe for the water that I used?

Answer 1

The amount you owe for the water that you used = (This month reading - Previous month reading) $\times$ Charges per ccf

$= (0289 ccf - 0286 ccf) \ times \$6.25$

$= 3 \times \$6.25\\ = \$18.75$

The amount you owe for the water that you used = $18.75
