Answer:
Decay, 36%
Step-by-step explanation:
.64 is less that 1, so it is a decay. You find the rate by using the equation 1 - .64 = .36 or 36%.
For compounding interests, we use the equation F = P (1+i)^n where F is the future amount of the principal amount, P, in n years. Take note that the interest to be used should be the effective interest rate. In this case, it is already the effective interest rate.
F = P (1+i)^n
F = $4000 (1+.055)^4
F = $4955.2986
1/3 of 45 is 15, meaning 15 students gave their speech on day 1
