Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for a total of $6.75, and 4 pieces of crab for $8.00. Which list shows the unit cost of each piece of sushi from least to greatest?

Question

squid, crab, tuna, eel
eel, squid, tuna, crab
squid, eel, crab, tuna
eel, tuna, crab, squid

Answer 1

To determine the unit cost of each piece of sushi, we need to calculate the cost per piece for each type of sushi ordered by Eva.

1. Squid:

   • Total cost for 2 pieces = $3.50
   • Unit cost = \( \frac{3.50}{2} = 1.75 \) (per piece)

2. Eel:

   • Total cost for 1 piece = $3.25
   • Unit cost = \( \frac{3.25}{1} = 3.25 \) (per piece)

3. Tuna:

   • Total cost for 3 pieces = $6.75
   • Unit cost = \( \frac{6.75}{3} = 2.25 \) (per piece)

4. Crab:

   • Total cost for 4 pieces = $8.00
   • Unit cost = \( \frac{8.00}{4} = 2.00 \) (per piece)

Now we have the unit costs:

• Squid: $1.75
• Crab: $2.00
• Tuna: $2.25
• Eel: $3.25

Ordering the unit costs from least to greatest:

1. Squid: $1.75
2. Crab: $2.00
3. Tuna: $2.25
4. Eel: $3.25

Thus, the correct order is: squid, crab, tuna, eel.

The answer is: squid, crab, tuna, eel.
