I dont know the answer to that
The Institutional changes between the 1960s and 1980s shifted the public policy from emphasizing public interest to upholding and satisfying the regulations. Among the greatly affected was the educational system. The structures of the different learning institutions were changed to accommodate dynamic market models and work around the expected outcomes of learning.
a = your total price before the coupon and sales tax.
b = your coupon's given discount (for example, 25% off)
c = your discounted total
(a - (ab)) = c
c + (.075c) = your answer.
With some numbers plugged in:
a = 50$, b = -25%
50 - (50 x .25)
50 - 12.5 = 37.50$
37.5 + (37.5 x .075)
37.5 + 2.82* = 40.32$
So you would have to pay $40.32
