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.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
