Steps to Solve
-
Calculate the discount amount The discount is 25% of $20. $$ Discount = 0.25 \times 20 = 5 $$ So, the discount amount is $5.
-
Calculate the discounted price Subtract the discount from the original price. $$ Discounted,price = 20 - 5 = 15 $$ The discounted price is $15.
-
Calculate the sales tax amount The sales tax is 5% of the discounted price, $15. $$ Sales,tax = 0.05 \times 15 = 0.75 $$ So, the sales tax amount is $0.75.
-
Calculate the final price Add the sales tax to the discounted price. $$ Final,price = 15 + 0.75 = 15.75 $$ Therefore, the final price Emma Lee pays is $15.75.
