Take the answer and divide it
Step-by-step explanation:
You have to use logarithms.
1) a = log_3 (1/27) = -log_3 (27) = -3
2) b = log_3 (9 * 3^(1/2)) = log_3 (3 ^ {5/2}) = 5/2
3) c = -log_3 (sqrt3) = -1/2
You do $23.85 minus $12.60. Which is 11.25 then divid the 11.25 by 2.25 That will give you the number of magazines which is 5 Magazines
