Answer:
$118.83 per month that Zach must save.
Explanation:
This is a future value annuity as we know the cruise will cost $16500 in 4 years time as estimated by Zach for the cruise.
Fv is the future value for the annuity which is $16500
we also have i the interest rate which is 3.99% monthly
n is the number of periods in which the monthly amount is saved 4 x 12 =48
now we will substitute to the following formula and solve for C the monthly payments that Zach saves for the cruise:
Fv =C [((1+i)^n -1)/ i] now we substitute
$16500 = C[((1+3.99%)^48 -1)/3.99%)] then solve for C
$16500/[(1+3.99%)^48 -1)/3.99%] = C
C = $118.83 that Zach must save per month for 4 years to afford the cruise.
