Answer:
405
Step-by-step explanation:
To find sample size, use the following equation, where n = sample size, za/2 = the critical value, p = probability of success, q = probability of failure, and E = margin of error.

The values that are given are p = 0.84 and E = 0.03.
You can solve for the critical value which is equal to the z-score of (1 - confidence level)/2. Use the calculator function of invNorm to find the z-score. The value will given with a negative sign, but you can ignore that.
(1 - 0.9) = 0.1/2 = 0.05
invNorm(0.05, 0, 1) = 1.645
You can also solve for q which is 1 - p. For this problem q = 1 - 0.84 = 0.16
Plug the values into the equation and solve for n.

Round up to the next number, giving you 405.
A customer will pay $225.5 for one rug.
Step-by-step explanation:
Given,
Purchase price of rug = $82.00
Mark up = 150%
Amount of mark up = 150% of purchase price
Amount of mark up = 
Amount of mark up = 1.5*82 = $123
Price of rug after mark up = Purchase price + Mark up
Price of rug after mark up = 82+123 = $205
Sales tax = 10%
Amount of sales tax = 10% of price after markup
Amount of sales tax = 
Selling price = Price after markup + Amount of sales tax
Selling price = 205+20.5 = $225.5
A customer will pay $225.5 for one rug.
