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=<span>1,891.25
then divide </span><span>1,891.25 by 85
x=</span>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.
I agree with Noah's Method because following PEMDAS you have to do exponents first. 10^3 is 1000 and then you can add the 20. Jada's method is incorrect because you cannot add the two together.
