Question

At the fish counter, salmon was selling for $9.60 a pound, white fish for $7.20 a pound, swordfish for $8.40 a pound, and haddock for $6.90 a pound. Sasha bought 3/4 lb. of fish for $5.40. What fish did he choose?

A. Swordfish
B. Salmon
C. Haddock
D. Whitefish

Answer 1

C. Haddock

Answer 2

To figure out which fish Sasha chose, we need to compare the total cost of the fish he bought with the price of each type of fish per pound.

Let's calculate the cost per pound for each type of fish:
Salmon: $9.60 per pound
White fish: $7.20 per pound
Swordfish: $8.40 per pound
Haddock: $6.90 per pound

Now, we can find the total price of the fish Sasha bought:
Total cost = $5.40

To find the weight of the fish, we'll divide the total cost by the price per pound. Let's check each type of fish:

For salmon:
Weight of salmon = $5.40 / $9.60
Weight of salmon ≈ 0.5625 pounds

For white fish:
Weight of white fish = $5.40 / $7.20
Weight of white fish ≈ 0.75 pounds

For swordfish:
Weight of swordfish = $5.40 / $8.40
Weight of swordfish ≈ 0.6429 pounds

For haddock:
Weight of haddock = $5.40 / $6.90
Weight of haddock ≈ 0.7826 pounds

From the calculations, we can see that the weight of fish Sasha bought is closest to 0.75 pounds, which corresponds to the weight of white fish.

Therefore, Sasha chose D. White fish.

Answer 3

To solve this problem, we need to determine the cost of each type of fish per pound. We can then compare the cost Sasha paid to the cost of each type of fish to figure out which one she chose.

First, let's find the cost of each type of fish per pound:
- Salmon: $9.60 per pound
- Whitefish: $7.20 per pound
- Swordfish: $8.40 per pound
- Haddock: $6.90 per pound

Next, we can compare the cost Sasha paid ($5.40) to the cost of each fish per pound.

We can use the equation:

Cost of fish = Cost per pound x Weight

We are told that Sasha bought 3/4 lb. of fish for $5.40.

Let's find the cost of each type of fish for 3/4 lb:

- Salmon: 3/4 lb x $9.60 per pound = $7.20
- Whitefish: 3/4 lb x $7.20 per pound = $5.40
- Swordfish: 3/4 lb x $8.40 per pound = $6.30
- Haddock: 3/4 lb x $6.90 per pound = $5.18

Comparing the cost Sasha paid ($5.40) to the costs we found, we can see that the cost matches the cost of the Whitefish ($5.40).

Therefore, Sasha chose the Whitefish.

The answer is D. Whitefish.
