I need help with this problem.

The electricity meter on Donna's house
read 71,236.4 kwh at the beginning of
March and 73,196.2 kwh at the end of
March. She pays 7.4% per kwh.
What is the amount of her electricity
bill for March? Round to the nearest cent.

Do I add the kwh's used and divide 7.4?
and round to the nearest cent.

Subtract the initial from the final kwh readings to get the amount consumed for the month: 1958.8 kwh. The cost per kwh is 7.4 cents, NOT 7.4%. (That is a pretty low rate nowadays). The product of the amount consumed and the rate is \$145.03 (after converting cents to dollars and rounding to the nearest cent)

which tool should be used to measure the mass of a bag of apples?
thermometer
inch ruler
produce scale
measuring cup

Take a wild guess. This is not a hard question.

thermometer duh
