By solving a linear equation, we conclude that after 3.57 hours, the prices of the two stocks are the same.
For stock A, the price started at $12.51 and it increased at a rate of $0.09 per hour. So after x hours, the price of stock A is:
A(x) = $12.51 + $0.09*x
For stock B, the price starts at $13.26 and it increases at a rate of $0.12 per hour, then the price after x hours is:
B(x) = $13.26 - $0.12*x
The price of the stocks is the same when:
A(x) = B(x), then we can solve the equation:
$12.51 + $0.09*x = $13.26 - $0.12*x
Now we can solve that linear equation for x:
$0.09*x + $0.12*x = $13.26 - $12.51 = $0.75
$0.21*x = $0.75
x = $0.75/$0.21 = 3.57
So, after 3.57 hours, the prices of the two stocks are the same.
