Answer:
The answer to the question is TRUE.
See below
Step-by-step explanation:
Circle equation standard form
(x-h)^2 + ( y-k)^2 = r^2 h, k is the center
All are centered at 0,0
radii are sqrt(225) = 15 sqrt 49 = 7 and sqrt 178
15
The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
The factors of 45 are: 1, 3, 5, 9, 15, 45
The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Then the greatest common factor is 15.

The price dropped by 0.08 dollars (subtract 3.20 and 3.12)
Divide this price drop over the original price
0.08/3.20 = 0.025 = 2.5%
The negative is to indicate a price drop or decrease
--------------
If you want, you can use the formula below
P = 100*(N - S)/S
where N = 3.12 is the new price and S = 3.20 is the start price, so
P = 100*(N-S)/S
P = 100*(3.12-3.20)/3.20
P = -2.5%
we get the same answer as before
