If you would like to know what is the value of a b in terms of b, you can calculate this using the following steps:
120% of a = 80% of b
120/100 * a = 80/100 * b /*100
120 * a = 80 * b /120
a = 80 / 120 * b
a = 2/3 * b
The correct result would be a = 2/3 * b.
It has been given that P - 15 is the amount paid after using a coupon on a purchase amount of P dollar.
So, 15$ is the coupon discount.
So now we have the following:
Actual Price: P$
Discount : 15$
So for a purchase of 83$, you will have to pay:
83 - 15 = 68$ [Substituting P with 83]
