A digital camera is on sale for 20% off the regular price of $599. After the price reduction, a 6.5% sales tax is added. How much will the customer pay?

20% off, means it came to 100% - 20% = 80%

80% of 599 = 0.8 * 599 = 479.2

6.5% of sale tax added, means 100% + 6.5% = 106.5%

= 106.5% * 479.2

= (106.5/100) * 479.2

= 1.065 * 479.2

= 510.348

Customer would pay $510.348 ≈ $510.35
