Answer 1
Answer:

Third month Gina's payrate will be $9.9 per hour.

Given that,

  • Currently earning $10 per hour.
  • Second month increase by 10%.
  • Next month  decrease by 10%.

According to the given data, calculation of the given data are as follows,

Second month earning = $10 + ( $10 * 10%)

= $10 + $1

= $11 per hour

Third month's earning = $11 - ( $11 * 10%)

= $11 - $1.1

= $9.9 per hour

So, third month pay rate will be $9.9.

Answer 2
Answer: So you start with $10, you calculate the 10%, then add it to it. This is the second month's pay. Now you have to calculate the 10%, then subtract this from the second month's pay. 

10% of $10 = $1
Second month's earning = $10 + $1 = $11
10% of $11 = $1.1
Third month's earning = $11 - $1.1 = $9.9
