The price of Stock A is $5 greater than the price of Stock B. If the price of Stock A increases by $10, the new price will be double the price of Stock B. What is the price of Stock B?

A 10
B 15
C 20
D 25
E 30
\(a = 5 + b\)

\(a + 10 = 2b\)

Or, \(2b - 10 = 5 + b\) (By substitution)

Or, \(b = 15\), Thus, ANswer must be (B)

let b = x
