1. **State the problem:** Vicky lost P17 on each of 5 Megahtron shares, lost P86 on one Optimus-Primeholdings share, and made a profit on one Bubblebiz share. Overall, she made a profit of P151 on all 7 shares. We need to find the profit on the Bubblebiz share. 2. **Define variables:** Let the profit on the Bubblebiz share be $x$. 3. **Write the equation:** Total profit = Profit from Bubblebiz + Loss from Megahtron + Loss from Optimus-Primeholdings. $$x + (5 \times -17) + (-86) = 151$$ 4. **Calculate losses:** $$5 \times -17 = -85$$ So the equation becomes: $$x - 85 - 86 = 151$$ 5. **Simplify the equation:** $$x - (85 + 86) = 151$$ $$x - 171 = 151$$ 6. **Solve for $x$:** $$x - 171 = 151$$ Add 171 to both sides: $$x - \cancel{171} + 171 = 151 + 171$$ $$x = 322$$ 7. **Answer:** The profit on the Bubblebiz share is P322.
