Monica bought a dress that was originally $60 and was 20% off. rachel found the same dress for $70 but at 25%. who paid less for the dress? how much less?

Monica paid less than Rachel. Monica paid 4.5$ less than Rachel

Solution:

Given that,

Monica bought a dress at 20 % off

Original price of dress = 60$

And Rachel bought same dress for 70$ at 25% off

Let us calculate the selling price of dress bought by both Monica and Rachel to find out who paid less

In case of Monica:

Original price = 60

discount % = 20 %

selling price = original price - 20 % of original price

selling price = 60 - 20% of 60

Hence Monica paid 48$

In case of Rachel:

Original price = 70

discount % = 25 %

selling price = original price - 25 % of original price

selling price = 70 - 25% of 70

Thus Rachel paid 52.5 $

When comparing the amount paid by Monica and Rachel, we observe that monica paid less

Difference between monica and rachel amount = 52.5 - 48 = 4.5

Thus monica paid 4.5$ less than rachel
