Answer:
The original price of the shoes was of 2200 pesos
Step-by-step explanation:
She bought the shoes for 1866 pesos.
She receibed a discount of 70 pesos, so the cost, with the discount, is 1866 + 70 = 1936 pesos.
The pair was bought at 12% off, that is, 1936 pesos is 100 - 12 = 88% of the original price. Then
[tex]0.88x = 1936[/tex]
[tex]x = \frac{1936}{0.88}[/tex]
[tex]x = 2200[/tex]
The original price of the shoes was of 2200 pesos
