Answer:
25%
Step-by-step explanation:
Since we know that the markdown is $20 by subtracting 80-60 , we find out what percent of 20 is 80. To do that you do 20/80, which is 0.25, or 25 percent.
-14+77=63
21-82=-61
|-61|=61
So 63-61=2
3.25kg
3.4kg
3256g
3500g
Factor the numerator and denominator and cancel the common factors.
-2x/-10 = x/5
