Salmon was $9.60 a pound, whitefish $7.20 a pound, and swordfish $8.40 a pound and haddock $6.90 a pound. Sasha bought 3/4 a pound of fish for $5.40 which fish did she buy

Answer 1

To find out which fish Sasha bought, we can determine how much each type of fish would cost if she bought 3/4 pound:

1. Salmon:

   • Price per pound = $9.60
   • Cost for 3/4 pound = \( 9.60 \times \frac{3}{4} = 9.60 \times 0.75 = 7.20 \)

2. Whitefish:

   • Price per pound = $7.20
   • Cost for 3/4 pound = \( 7.20 \times \frac{3}{4} = 7.20 \times 0.75 = 5.40 \)

3. Swordfish:

   • Price per pound = $8.40
   • Cost for 3/4 pound = \( 8.40 \times \frac{3}{4} = 8.40 \times 0.75 = 6.30 \)

4. Haddock:

   • Price per pound = $6.90
   • Cost for 3/4 pound = \( 6.90 \times \frac{3}{4} = 6.90 \times 0.75 = 5.175 \)

From the calculations:

• Salmon would cost $7.20 for 3/4 pound.
• Whitefish would cost $5.40 for 3/4 pound.
• Swordfish would cost $6.30 for 3/4 pound.
• Haddock would cost about $5.18 for 3/4 pound.

Since Sasha spent exactly $5.40, she must have bought whitefish.
