1 over 64
8^2 = 64 , 8^-2 = 1/(8^2) = 1/64
So the original price is 40 dollars. We can see how much she saved by multiplying the original amount with the discount. 40 x .60=24. So she saved 24 dollars. We can then subtract 24 from 40 to get a price of 16 dollars.
19. 19.31 times 40=$772.4
20. 52 times 772.4=$40,164.8
weekly = 40 times 19.31
yearly =weekly times 52 or 19.31 times 40 times 52
21. 15.07 times 40=$602.8
22. 52 times 602.8=$31,345.6
weekly = 40 times 19.31
yearly =weekly times 52 or 15.07 times 40 times 52
23. Monica yearly-Chris yearly=40,164.8-31,345.6=$8816.2
