You put $200 at the end of each month in an investment plan that pays an apr of 4.5%. how much will you have after 18 years? compare this amount to the total deposits made over the time period. a. $66,370.35; $43,200 b. $66,295.23; $43,000 c. $66,380.12; $43,000 d. $66,373.60; $43,200

Use the formula of the future value of annuity ordinary to find the total amount and interest at the end of 18 years
The formula is
Fv= pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value?
PMT monthly payment 200
R interest rate 0.045
K compounded monthly 12
N time 18 years
Fv=200×(((1+0.045÷12)^(12
×18)−1)÷(0.045÷12))
=66,373.60 answer

Then find the amount without implying the interest
200×12months×18 years=43,200...answer

So the answer is d

Hope it helps!
