I believe it’s the last one, but I could be wrong.. The n three times= 3n+15 (less than itself)-n ??
This is an example hope this helps
To find the answer to this problem, you can use the unit circle to see that pi over 6 radians is equal to 30°
Another way is to use the equation: degrees = radians • (180 over pi)
In this example, plugging in the radians portion of the equation gives us: degrees = (pi over 6) • (180 over pi), which will become degrees = (180pi over 6pi)
Simplify and pi cancels out to give us degrees = 30
Answer: 30°

since t=325 m, m=19
so t=325*19=$6175
Money made on memberships in a year:
12*$6175=$74100
