Answer:
V=10
Step-by-step explanation:
1st Group like terms: 6v-9v+18=-12
2nd Add similar elements: 6v-9v=-3v
-3v+18=-12
3rd Subtract 18 from both sides: -3v+18-18=-12-18
4th Simplify: -3v=-30
5th Divide both sides by -3: -3v÷-3=-30÷-3
6th Simplify: V=10
The worth of Sarah's investment when she is 68 is $14,728.51.
<h3>What is the worth of the investment?</h3>

FV = Future value
P = Present value
R = interest rate
N = number of years = 68 - 18 = 50
$500 x (1.07)^50 = $14,728.51
