15% off
Step-by-step explanation:
We know we paid $25.50 of the original $30. We can divide these two numbers 
. This is means we paid 85% of the original price. The discount percentage is the remaining percentage from 85 to 100 which is 15. The pants were 15% off.
Answer:
first one is a and the second one is c
To find the midpoint, add x1 and x2 then divide by 2, then add y1 and y2 and divide by 2.
Midpoint = (2a +2b /2 , 0 + 2c /2)
Midpoint = a+b, c
Absolute value means the total distance from zero. So you get rid of any negative signs and then look at which number has the lowest value (which is the smallest number without any negative signs).
15 divided by 6 2/3 is 2.25. Or 2 1/4. Pick C
