Answer:

Last year Jules' contract was for 1200 hours.

Step-by-step explanation:

This year Jules has a contract to work for 984 hours.

This is an 18% decrease on the hours on last year's contract.

Last year number: x

This years: 100 - 18 = 82% of last year, which is 984 hours. This means that:

0.82x = 984

x = \frac{984}{0.82}

x = 1200

Last year Jules' contract was for 1200 hours.

Grovell works at Walmart. He earns $12 per hour. The store offers him a raise of 5% increase per hour.
DerKrebs [107]

Answer:

$ 12.6 / h

Step-by-step explanation:

5% of 12 = 0.05 * 12 = 0.6

Now adding it to the amount he makes, since it is a raise:

0.6 + 12 = 12.6 $ / h

Another (and faster) way to calculate it:

1.05 * 12 = 12.6
