If karen works 85 hours within two weeks and earns $1,891.25, you'd set up an equation like this, to find the value of x ----
x=amount of money per hour Karen works
85x=1,891.25
then divide 1,891.25 by 85
x=22.25
this says that karen gets $22.25 for every hour she works.... then to find how much she works for 8 hours you want to multiply the amount of money she gets per hour by 8 hours.
22.25 x 8 = 178
Karen earns $178 after working 8 hours.
