Answer:
Percent Change Formula: [(new - old)/old] * 100
Step-by-step explanation:
New - old
80 - 20 = 60
Difference between new - old divided by old
60/20 = 3
Previous quotient times 100
3*100 = 300
Percent Change is 300%
Check your answer
300% of 20 is 60
20 + 60 = 80
The first two rows of coefficients are identical, so by inspection, the determinant is 0.
