The amount of decrease is (80 - 64) = 16

The fraction of decrease is the fraction of the original amount that disappeared.

That fraction is (16 / 80) = 1/5 = 0.2

To change a decimal to a percent,
move the decimal point 2 places that way ==> .

Answer:

h = 13.333 +693.333/r

Step-by-step explanation:

For h hours, Brandee's pay will be ...

pay = 40r +(h -40)(1.5r) . . . . 40 hours at rate r + overtime (h-40) hours at 1.5r

pay = 40r +1.5hr -60r . . . . . eliminate parentheses

pay = 1.5hr -20r . . . . . . . . . . collect terms

Solving for h, we have ...

pay +20r = 1.5hr . . . . . . . . . . add 20r

h = (pay +20r)/(1.5r) . . . . . . . . divide by 1.5r

For the given pay of 800 +240 = 1040, we have ...

h = (1040 +20r)/(1.5r)

h = 13.333 +693.333/r . . . . . simplify to 2 terms

<em>Additional comments</em>

You need to know r to find the number of hours Brandee worked. She got paid $800 for a presumed 40-hours of regular time, so made r = $20 per hour. The above formula will tell you she worked 48 hours in the pay period.
