To find the total cost that Gabriel will pay, we need to start by calculating the total cost of the apples and the lettuce:
1. **Cost of apples**: He bought 2.5 pounds of apples at x dollars per pound, so the cost of apples is \(2.5x\).
2. **Cost of lettuce**: He bought 2 bags of lettuce at y dollars each, so the cost of lettuce is \(2y\).
Next, we can sum these costs to find the total bill before applying the coupon:
\[
\text{Total cost} = 2.5x + 2y
\]
Now, because Gabriel has a coupon for $2 off, we subtract 2 from the total amount:
\[
\text{Total cost after coupon} = (2.5x + 2y) - 2
\]
This simplifies to:
\[
2.5x + 2y - 2
\]
Thus, the expression that gives the new amount Gabriel will pay is:
**2y + 2.5x - 2**

Yes, let me break it down again step-by-step to ensure clarity and correctness.
1. **Cost of the apples**: Gabriel bought 2.5 pounds of apples at \(x\) dollars per pound. The total cost for the apples is calculated as:
\[
2.5 \times x = 2.5x
\]
2. **Cost of the lettuce**: Gabriel bought 2 bags of lettuce at \(y\) dollars each. The total cost for the lettuce is:
\[
2 \times y = 2y
\]
3. **Total cost before the coupon**: To find the total amount before any discounts, we add the cost of the apples and the cost of the lettuce:
\[
\text{Total cost} = 2.5x + 2y
\]
4. **Applying the coupon**: Since Gabriel has a coupon for $2 off, we subtract $2 from the total cost:
\[
\text{Total cost after coupon} = (2.5x + 2y) - 2
\]
Which simplifies to:
\[
2.5x + 2y - 2
\]
So, the correct expression for the amount Gabriel will pay after applying the coupon is indeed:
**2y + 2.5x - 2**
