Answer:
So she will earn a total of $734.4 in 40 hours at new rate
Explanation:
Given:
Maggie was earning at $15.30
Raise = 20%
To find:
She earns in 40 year at new rate
Solution:
New rate per hour = Old rate + Raise
Now we have to first find the raise in dollars
Raise = 20 % of old rate
Putting in value
Raise = 20 % of 15.30
It could be written as
Raise =
![(20)/(100)*15.30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mjx78rd005a8cfkmbp751yspalixe0i8dg.png)
Raise =
![(306)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/dgpjqv764ueaepwjirjqdr924hzgwxnwiu.png)
Raise = $ 3.06
New rate = old Rate + Raise
= $ 15.30 + $ 3.06
=$18.36
Total money earned = Total hours * New rate
= 40 * $ 18.36
=$734.4
So she will earn a total of $734.4 in 40 hours at new rate
