D) c=3p+2 3 caterpillars per plant and 2 on ground
They weigh the same because a pound is a pound.
Beginning with the last deposit and working toward the present, the amount in the account is
3000 + 3000*1.06 + 3000*1.06^2 + 3000*1.06^3 + 3000*1.06^4
= 3000*(1.06^5 -1)/(1.06 -1)
= 16,911.28 . . . dollars
_____
The sum is found using the formula for the sum of a geometric series. For first term a1 and common ratio r, that sum is
Sn = a1*(r^n -1)/(r -1)
Your series has a1=3000 and r = 1.06. It has 5 terms (n=5).
