Question

Maggie was earning $15.30 per hour at the beginning of one year then got a 20% raise without deductions how much will she earn by working 40 hours at the end the new rate

Answer 1

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`

Raise =
`(306)/(100)`

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
