Question

( PLEASE HELP ME ANY ANSWERS !!!!) A jewelry store purchases necklaces for n dollars each. The necklaces are then marked up by 20%, and customers are charged 5% sales tax on the selling price. The expression n +(20%times n) represents the selling price. Write and simplify an expression to represent the price a customer pays after sales tax is collected. Show your work. Explain the meaning of the expression

Answer 1

1.14n

Explanation:

if n+(0.20n) represents the selling price, and we are charged with a 5% sales tax then we just need to multiply the selling price by 0.05 and subtract the result from the selling price(sales tax means the selling cost decreases, which is why we subtract)

so

n+0.20n-(0.05(n+0.20n))

2)distribute

n+0.20n-0.05n+0.01n

3) combine like terms

1.20n-0.06n=1.14n

1.14n is the price after salestax is collected

Hope this helps!
