Answer:
10.67% increase
Step-by-step explanation:
We can find percent increase with (difference/original) x 100
7.47 - 6.75
= 0.72 (difference)
(0.72/6.75) x 100
= 10.67% increase
The answer is A. because for you to find the answer you have to subtract so it would be 55.75-12.5=43.25
Because we don't have any set numbers for x or y, I believe that the solution set for both equations are infinite.
