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 pieces of sushi from least to greatest?

Answers

The price of each piece of sushi is required.

The cost of each piece of sushi from least to greatest is squid ($1.75), crab ($2), tuna ($2.75) and eel ($3.25)

$2\ \text{pieces of squid}=\$3.5\n\Rightarrow 1\ \text{piece of squid}=(3.5)/(2)=\$ 1.75$

1 piece of squid costs $1.75.

1 piece of eel costs $3.25.

$3\ \text{pieces of tuna}=\$6.75\n\Rightarrow 1\ \text{piece of tuna}=(6.75)/(3)=\$ 2.25$

1 piece of tuna costs $2.75.

$4\ \text{pieces of crab}=\$8\n\Rightarrow 1\ \text{piece of crab}=(8)/(4)=\$ 2$

1 piece of crab costs $2.

2 pieces of squid = $3.50
Therefore 1 piece of squid = $1.75 (3.50÷2)

1 piece of eel = $3.25

3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)

4 pieces of crab = $8.00
Therefore 1 piece of crab = $2 (8÷4)

Put them in order of price and you get

$1.75 , $2 , $2.25 , $3.25
squid,crab,tuna,eel
