219+159≤x≤369+309
The answer can then be simplified to
378≤x≤678
Answer: It was marked down by 35%
Step-by-step explanation:
1. find the difference of the two prices, 68-44.20=23.8
Take the fraction 23.8/68 (because that is how much the price changed and you need to find what percent that is.
You get 35%
no because one is negative and the other is positive so no it didn't
A-
-$12.58
B-
-$37.58
C-
You need $37.58 to bring it back up to $0
So you move left to right like PEMDAS when it comes to adding or subtracting either or could go first and same thing applies with multiplying and dividing so for instance in this case
47*7=329
_
329/9=36.5
