Let x be her regular hourly wage; then 2.5x is her hourly overtime pay.

Her earnings for 40 hours of regular time plus 8 hours of overtime are $1230:

40%28x%29%2B8%282.5x%29+=+1230

Solve using basic algebra.

Informally, each hour of overtime is like 2.5 hours of regular time, so 8 hours of overtime is like 8*2.5 = 20 hours of regular time.

So her $1230 earnings are for 40+20 = 60 hours of work.

Her regular hourly wage is $1230/60.

Perform the calculation.

.

The basic equation is


    40x + 2.5*(48-40)*x = 1230.


Simplify and solve for x


    40x + 2.5*8x = 1230

    40x + 20x    = 1230

    60x          = 1230

      x           = 1230%2F60 = 20.50 dollars.    ANSWER
