Apromotional sale at department store offers 25% off the sale price. the sale price is 25% off the regular price. is this same as a sale that offers 50% of regular price? ( try both with a coat whose original cost was $100

This is not the same. The 50% discount would be better.

Step-by-step explanation:

The reason for this is that when you take 25% off the already marked down price, you are not getting 25% off the whole $100. As a result, you wind up getting less off. See the example below.

$100 (cost) - $100*25% (discount) = Sale Price

$100 - $25 = Sale Price

$75 = Sale Price

$75(Sale Price) - $75*25%(Promo) = Overall price

$75 - $18.75 = Overall price

$56.25 = Overall price

This is the cost of the two discounts, whereas if you take all 50% at once, you'll only pay $50.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
