Question

At Best Buy they have a stereo system that sells for $2500 and is on sale for 9% and sales tax is 5%. What is the final cost?

Answer 1

Final cost = $2388.75

Explanation:

Cost of stereo system = $2500

Sale = 9%

Cost of sale = 9% of 2500

Cost of sale =
`(9)/(100)*2500 = 0.09*2500`

Cost of sale = $225

Price after sale = 2500 - 225 = $2275

Sales tax = 5% of 2275

Sales tax = 0.05 * 2275 = $ 113.75

Final cost = 2275 + 113.75 = $2388.75
