To find the correct expression for the new amount Gabriel will pay, we first need to set up his total costs before applying the coupon.
1. The cost for apples is calculated as:
- 2.5 pounds of apples at x dollars per pound: \( 2.5x \)
2. The cost for the bags of lettuce is:
- 2 bags at y dollars each: \( 2y \)
3. Therefore, the total cost before applying the coupon is:
- Total cost = Cost for apples + Cost for lettuce = \( 2.5x + 2y \)
4. Gabriel has a coupon for $2 off, which means we subtract $2 from the total cost:
- New total = \( (2.5x + 2y) - 2 \)
This gives us the expression:
\[
2.5x + 2y - 2
\]
Looking at the choices provided, we see:
- \( 4.5hy -2 \)
- \( 2y + 2.5x + 2 \)
- \( 2.5у + 2x - 2 \)
- \( 2у + 2.5^2 - 2 \)
None of the options provided match the derived expression \( 2.5x + 2y - 2 \) exactly. However, we can see that the expression \( 2.5y + 2x - 2 \) is incorrect because it has the wrong variables.
If correcting for potential misprints, only one possibly resembles our logic closely, though not perfectly:
It looks like the closest correct expression should have been:
\[
2.5x + 2y - 2
\]
Since none of the given options fully match, based on derivation, our closest derived answer would be \( 2.5x + 2y - 2 \).
