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
