PLSSSSSSSSSSSSSSSSSSSSSSSSSSSSS HELP ME
Ash cannot decide which of two washing machines to buy. The selling price of each is ​$360. The first is marked down by ​30%. The second is marked down by 10​% with an additional ​20% off. Find the sale price of each washing machine. Use pencil and paper. Explain why ash should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answer:

The answer is the first one.

Step-by-step explanation:

Okay, so the first one is solved like this:

You do 360*30%. 30% is 0.3 in decimal form. So 360*0.3=108. 108 is the amount that is discounted, NOT the price. You have to do 360-108, which is 252. The discounted price is $252.

Now the second one is solved like this:

You do 360*10% FIRST because the problem says it was marked 10% BEFORE the 20%. 10%=0.1, so 360*0.1=36. You subtract 360-36, which is 324. Then, you multiply 324 by 20% or 0.2, to get 64.8, which is the discount of 20%. You subtract 324-64.8, which is $259.20. So the first one is the answer because it is cheaper since 252 is less than 259.20. If you need this explanation, don't use this word for word. Summarize this in YOUR own words!
