1. **State the problem:**
Jessie is planting a trapezoid-shaped garden with bases and height given. We need to find the area of the trapezoid.
2. **Formula for the area of a trapezoid:**
$$\text{Area} = \frac{(\text{Base}_1 + \text{Base}_2)}{2} \times \text{Height}$$
3. **Identify given values:**
- Base one, $\text{Base}_1 = 12.5$ feet
- Base two, $\text{Base}_2 = 0.5 \times 12.5 = 6.25$ feet
- Height, $h = 10$ feet
4. **Calculate the area:**
$$\text{Area} = \frac{(12.5 + 6.25)}{2} \times 10$$
5. **Simplify inside the parentheses:**
$$12.5 + 6.25 = 18.75$$
6. **Substitute back:**
$$\text{Area} = \frac{18.75}{2} \times 10$$
7. **Simplify the fraction:**
$$\text{Area} = 9.375 \times 10$$
8. **Multiply:**
$$\text{Area} = 93.75$$
9. **Answer:**
The area of the garden is **93.75 square feet**.

1. **State the problem:**
Michael compares two discount methods on a $495 television to see if they yield the same sale price.
2. **Manager's method:**
- First discount: 20% off original price
- Second discount: 25% off the reduced price
3. **Michael's method:**
- Single discount: 45% off original price
4. **Calculate manager's sale price:**
First discount price:
$$495 - 0.20 \times 495 = 495 \times (1 - 0.20) = 495 \times 0.80 = 396$$
Second discount price:
$$396 - 0.25 \times 396 = 396 \times (1 - 0.25) = 396 \times 0.75 = 297$$
5. **Calculate Michael's sale price:**
$$495 - 0.45 \times 495 = 495 \times (1 - 0.45) = 495 \times 0.55 = 272.25$$
6. **Compare prices:**
- Manager's final price: $297$
- Michael's final price: $272.25$
7. **Conclusion:**
Michael is incorrect because his method results in a lower price than the manager's method.
**Answer:** A) No, Michael’s method has a greater effect on the sale price.
