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

Answer 1
Answer:

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.

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

Answer 2
Answer: 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

How to solve and figure it out

Answers

so your equation is currently in point-slope form; however, to figure out the slope and y-intercept, you'd be better off in slope-intercept form: y = mx + b

while in point-slope form, y - y1 = m(x - x1), you can definitely see the slope as -5, you can't see the y-intercept as easily. x-intercepts are actually the solutions/zeros of a function, and it was included in the answer choices to confuse you.

you're correct about -5 being a decreasing slope. but to figure out the y-intercept, you need to convert to slope-intercept form.

y - 4 = -5(x + 1)  ... distribute the -5
y - 4 = -5x - 5  ... add 4
y = -5x - 1

and in the form of y = mx + b, where m is the slope and b is the y-intercept, you can see that you have a decreasing slope of -5 and a y-intercept of -1. your correct answer is A. choices C and D were thrown in to distract you and make you think that the -5(x + 1) was somehow related to discovering the x-intercept.
