Answer:
$9,945
Step-by-step explanation:
Principal = $8,500
Rate = 17% = 0.17
Number of times compounded in a year, n = 1
Period, t = 1 year
Amount, A = P(1 + r/n)^tn
A = 8500( 1 + 0.17/1)^ 1*1
A = 8500( 1.17)^1
A = $9,945
$190*3=$570
$0.20*600= $120
$570+$120= $690
Total cost of trip is $690
Answers:
- Sam's current age = 24
- The mother's current age = 48
=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.
