Ella earns 1.5 her normal hourly rate for overtime pay. Last week, Ella earned $72.00 in overtime pay for 4 hours. What is Ella'
mr_godi [17]

Answer:

Ella's normal hourly pay is $12 per hour.

Step-by-step explanation:

Let us assume that the Ella's Normal hourly pay = $x per hour

Over hourly pay = 1.5 times ( Normal pay)

                           = 1.5 ( x)  =  $ 1.5 x

⇒Ella earns $1.5x in 1 hour of overtime.

So the amount she earns in 4 hour of overtime =  4 times (per hour pay)

                                                                                = 4 ( $1.5x)   = $ 6 x

The amount Ella earned in 4 hours of over time = $72.00

According to the question:

$ 6 x  = $72.00

or, x = 72/6

       =12

or , x  =  $12

Hence, Ella's normal hourly pay is $12 per hour.
