Explanation:
So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.
Where, the original price is the total price. So, the means that it is the whole price.
Just to help:
Answer - Part B: The original cost of the jeans are $80.
Step-by-step explanation:
If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.
So, see? 30% of 80 is $24.
