30 + 20 + 30 + 20 = 100
30 x 10% = 3 + 30 = 33
20 x 5% = 1 + 20 = 21
33 + 21 + 33 + 21 = 108
100 / 108 = 0.925925926 = 0.93 = 93%
100% - 93% = 7%
7% increase
The answer is correct
but I think in step 2 that should read the Associative property
Answer:

Step-by-step explanation:
Remember that the equation of the line is

in this case we have

that is because

Answer:
y=5*3^x
Step-by-step explanation:
y=5*3^(-1) =5/3
y=5*3^0=5*1=5
y=5*3^1=5*3=15
