Question

Eric bought a laptop for 664 it was marked 50 off because it was an opened product he also got a 15% discount which was taken off the original price what was the original price

Answer 1

The original price of the laptop is 840

Explanation:

Here, we want to calculate the original price of a laptop, given the amount that was paid off and the discount percentage enjoyed.

Firstly, let’s add back the 50 taken off. That makes a total of 50 + 664 = 714

Now, we remember he was also given 15% off. Let the price paid be x;

The 15% of x is equal the difference between x and the 714

Thus;

15/100 * x = x - 714

15x/100 = (x-714)

15x = 100(x-714)

15x = 100x -71400

100x-15x = 71400

85x = 71400

x = 71400/85

x = 840
