D. haddock

Answer 1

To determine which fish Sasha bought, we need to compare the cost of 3/4 lb. of each type of fish to the $5.40 he spent.

1. Salmon:

   • Price per pound: $9.60
   • Cost for 3/4 lb: \( \frac{3}{4} \times 9.60 = 7.20 \)

2. Whitefish:

   • Price per pound: $7.20
   • Cost for 3/4 lb: \( \frac{3}{4} \times 7.20 = 5.40 \)

3. Swordfish:

   • Price per pound: $8.40
   • Cost for 3/4 lb: \( \frac{3}{4} \times 8.40 = 6.30 \)

4. Haddock:

   • Price per pound: $6.90
   • Cost for 3/4 lb: \( \frac{3}{4} \times 6.90 = 5.18 \)

From the calculations:

• Salmon: $7.20
• Whitefish: $5.40
• Swordfish: $6.30
• Haddock: $5.18

Sasha spent $5.40, which matches the cost of 3/4 lb. of whitefish.

Therefore, the correct answer is:

C. whitefish
