Answer: 50 dollars
==================================================
Work Shown:
x = original price
y = sale price
d = discount = amount saved
d = 12% of x = 0.12x
y = x - d = x - 0.12x = 0.88x
Note how 0.88 = 88%, and this represents the percentage you have to pay if you get 12% off.
We're told the sale price is y = 44, so this leads to...
y = 0.88x
44 = 0.88x
0.88x = 44
x = 44/0.88
x = 50
The original price was $50
---------------------
Check:
If the original price was $50, then the amount you save is 0.12*50 = 6 dollars, which is the discount.
The sale price is 50-6 = 44 dollars which matches up with what your teacher gave you. The answer is confirmed.
