The total cost is $175.
The first thing that you need to do is calculate the per day cost per person.
$60 was spent on a three day trip. $60/2 = $20 per day. There were 4 adults on the trip, so $20/4 = $5. The cost of food is $5 per person per day.
On a trip with 7 adults the formula to solve the total cost is:
7 adults x 5 days x $5/day = $175.
<span>For the amount invested in the 20 year annuity immediate,
the return will be;
r/(1 - (1+r)^-n) = 0.05/(1- 1.05^-20)
= 0.0802425872
= 8.02425872%
Now, return on perpetuity-immediate = 5%
So, 5% + </span>8.02425872% = 13.02425872<span>
for equal returns from both investments,
X = 5/(13.02425872) x 640,000
= $245,695.365
= $ 245,695.36 </span>
