john bought a new mac laptop for 520.99 with 15% sales tax. what was the original price and tax?

1.15x = 520.99

x = 520.99/1.15

x = 453.03 >> original price

520.99 - 453.03 = _______ tax

Price * (1+0.15) = 520.99

Solve for price.

Tax is the difference between 520.99 and the original price.

thanks

To find the original price and tax, we need to work backwards from the given final price.

Step 1: Calculate the amount of sales tax:
The final price is $520.99, which includes 15% sales tax. To find the amount of sales tax, we need to calculate 15% of the final price:
Sales Tax = (15/100) * Final Price = 0.15 * 520.99 = $78.15

Step 2: Calculate the original price:
The original price is the final price minus the sales tax:
Original Price = Final Price - Sales Tax = $520.99 - $78.15 = $442.84

So, the original price of the Mac laptop was $442.84 and the tax was $78.15.
