Answer:
The credit card purchase price of the same item is $87.5
Step-by-step explanation:
Here, we are interested in calculating the credit-card purchase price of an item if we are given the cash price
Since there is a 4% discount on the cash; the percentage paid will be 100-4% = 96%
So what we are saying is that, it is 96% of the credit cash purchase that was paid as cash;
Let the credit card purchase be $x
96% of x = 84
96/100 * x = 84
96x = 100 * 84
x = 8400/96
x = 87.5
Thus, the credit card purchase price of the same item is $87.5
