Apair of boots originally priced at $129.99 were on sale for $103.99.
a) find the percent discount to the nearest tenth.
b) what sale price would represent a 25% discount from the original price?

pl

a) 20% rounded

b) $97.49

Step-by-step explanation:

a) $129.99 is the original price and represent 100% of the price for the item. When the item goes on sale for 103.99, it has been marked down x percent from 100%. To find this percent, write a proportion with these values:

Sole for x to find the percent you pay by cross multiplying numerator and denominator of each fraction.

103.99(100)=129.99(x)

10399=129.99x

79.99=x

80=x

b) If the discount is 25% then you pay 75% of the original price. Since the original price is 129.99 then you pay 0.75(129.99) = 97.49. You would pay $97.49.

This means you 80% of the original price and you receive as a discount the rest of the 20%.
