I can buy office supplies @ walmart with a 30/10 chain discount. If I paid $47.25 for adding machine. What was the regular price of my purchase?
30/10 chain discount means .70 x .90
regular price*.7*.9=47.25
regular price= 47.25/.63
To find the regular price of your purchase, we can use the formula:
Regular price = Discounted price / (Discount 1 as a decimal) / (Discount 2 as a decimal)
In this case, the discounted price is $47.25, and the chain discount is given as a multiplication of 0.70 (30% discount) and 0.90 (10% discount). So, we can substitute the values into the formula:
Regular price = $47.25 / 0.70 / 0.90
To calculate that, divide $47.25 by 0.70 to get the price before the first discount, then divide the resulting amount by 0.90 to get the price before the second discount:
Regular price = $47.25 / (0.70 * 0.90)
Regular price = $47.25 / 0.63
Regular price ≈ $75
Therefore, the regular price of your adding machine purchase was approximately $75.
