Question

Dave owns 15 shares of ABC mining stock. On Monday the value of each share rose $2 but on Tuesday the value fell $5. What is the change in the value of daves shares?

Answer 1

Let's take each share by itself first.
First, the value of each share rose by 2. So we have +2. Then it fell by 5. So we have 2 - 5 = -3. Each share has a net value of negative 3.
Dave owns 15 shares. So 15 * (-3) = -45.
-$45
