Question

A. $35.00

B. $70.00

C. $71.43

D. $100.00

Answer 1

The original cost of the skates before the 30% discount was $71.43, which is found by dividing the paid amount, $50.00, by 0.70 (100% - 30% discount).

Step-by-step explanation:

Susie paid $50.00 for some skates after a 30% discount. In order to find the original cost, we should consider that Susie paid 70% of the original cost because a 30% discount implies that only 70% of the original price must be paid. To find the original price, we can set up the equation where 70% of the original price (OR) is equal to $50.00:

0.70 * OR = $50.00

To find OR, we need to divide $50.00 by 0.70:

OR = $50.00 / 0.70

OR = $71.43

Therefore, the original cost of the skates before the discount was applied was $71.43, which is option C.
