Final answer:
To determine the final price Janice pays for the briefcase, information about the sale discount and any applicable sales tax is needed. With the provided example of Emily's jacket purchase, we first calculate the sales tax on the original price, round it to the nearest penny, and then add it to the original price to find the total cost.
Step-by-step explanation:
To calculate the amount Janice pays for the briefcase, we need to know the discount rate of the sale or if any other additional charges like sales tax apply. Since that information is not provided, we cannot accurately determine the final price Janice will pay. However, if we take a similar example: Emily bought a jacket for $85. If the sales tax is 7.5%, find the total cost of the jacket. To do this, first, we calculate the amount of sales tax by multiplying the original price by the sales tax rate.
For Emily's jacket:
- Calculate the sales tax amount: $85 * 0.075 = $6.375
- Round to the nearest penny: $6.38
- Add the original price of the jacket and the sales tax: $85 + $6.38 = $91.38
Applying this procedure to Janice's briefcase purchase, we would need to calculate the sale discount and add any applicable sales tax to find out how much she actually pays.
