1. **State the problem:** You currently have a budget of 100 per month for office snacks, and you want to increase this amount by 50% for next year. 2. **Formula used:** To increase a quantity by a percentage, use the formula: $$\text{New amount} = \text{Original amount} \times \left(1 + \frac{\text{Percentage increase}}{100}\right)$$ 3. **Apply the formula:** Here, the original amount is 100 and the percentage increase is 50, so: $$\text{New amount} = 100 \times \left(1 + \frac{50}{100}\right) = 100 \times 1.5$$ 4. **Calculate the new budget:** $$100 \times 1.5 = 150$$ 5. **Interpretation:** Next year's budget will allow 150 per month for office snacks, which is a 50% increase from the current 100. **Final answer:** Next year's budget for office snacks per month is 150.
