Answer: $9.
Step-by-step explanation:
It is given that,
Regular price of a new chair = $75.00
This week the chair will be on sale at a 12% discount. So,
Rate of discount = 12%
We need to find the amount of money that will Jessica save if she buys the chair this week.
![Discount=12\%\text{ of }\$75.00](https://tex.z-dn.net/?f=Discount%3D12%5C%25%5Ctext%7B%20of%20%7D%5C%2475.00)
![Discount=75\times \dfrac{12}{100}](https://tex.z-dn.net/?f=Discount%3D75%5Ctimes%20%5Cdfrac%7B12%7D%7B100%7D)
![Discount=9](https://tex.z-dn.net/?f=Discount%3D9)
Therefore, Jessica will save $9 if she buys the chair this week.
The answer is b because 5*20=100
