Can someone please answer step by step? Jane wants to buy a jacket that costs $75 but that is on sale for 20% off. She also has a coupon for 10% off. She tells her friend George that she can calculate the discounted price of the jacket by finding 30% of $75. George disagrees and states that she first needs to find 20% of $75 and then find 10% of your answer. Who is correct and why?

George is correct

Step-by-step explanation:

if the jacket is in sales for 20% off, Jane's coupon would give her a discount of 10% on top of the already discounted 20%.

Jane is incorrect because, if she added the 2 discount together, she gets a total of 30%, but that is a 30% discount of the original price of $75 which isn't correct. what we want to do is find how much the jacket cost after 20% discount THEN use the coupon to get a further 10% discount on the sales price of the jacket. and for this reason, George is correct.

hope this helped

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
