Answer:
a) 20% rounded
b) $97.49
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:
![(103.99)/(129.99)=(x)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/qnq8g5ndbuxmdo3iyp7430ek1ssul9g4ko.png)
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%.
