a computer costs 400 dollars. Its 20 percent off with an additional 5 percent off, there's no sales tax. How much does the compu

zhenek [66]

The computer costs $304 now.

Step-by-step explanation:

Given,

Cost of computer = $400

First discount = 20%

Amount of discount = 20% of $400

Amount of discount = $\frac{20}{100}*400=\frac{8000}{100}$

Amount of discount = $80

Price after first discount = 400-80 = $320

Additional discount = 5%

Amount of additional discount = 5% of price after first discount

Amount of additional discount = $\frac{5}{100}*320=\frac{1600}{100}$

Amount of additional discount = $16

Final cost = 320-16 = $304

The computer costs $304 now.
