Question

2. You have $60 to buy fish for a 30 gallon aquarium. Each angelfish costs $12 and needs at least 6 gallons of water. Each neon tetra costs $3 and needs at least 3 gallons of water. How many of each kind of fish can you buy?

Answer 1

So I am going to let x = the number of angelfish and y = the number of neon tetras.

Answer 2

But I am stuck from here.

Answer 3

you can buy 4 angel and 2 neon..

Answer 4

You're an angel! I have to show my work though >.<

Answer 5

Is that a question about probability O.O ?

Answer 6

Then I have to graph it :/

Answer 7

Well the paper is called 'find the errors'. They pretty much do the problem, but they mess it up and you have to find the error that they made and redo the entire problem and show it.

This is what they did"

Cost 12x+3y<=60
y<=-4x+20

Water: 6x+3y<=30
y<=-2x+10

Answer 8

So no, it isn't a probably question.

Answer 9

just solve for x and y :D

Answer 10

and the graph is easy...

Answer 11

I just have to graph 4 and 2, right?

Answer 12

Word problems are not my talent at all!

Answer 13

what values did you get for x and y ?

Answer 14

x = 4 and y = 2

Answer 15

Equation : y = -4x + 20
x cannot be negative... and x should be equal to 1 or greater..

Answer 16

suppose x = 1, y = -4 (1) + 20 = ....
then Coordinates : ( 1 , 16 )

Answer 17

I'm with you so far

Answer 18

then x = 2 , y = _____
x = 3 , y = ______
x = 4 , y = __________

Answer 19

I am confused on where to go from here to find the answer

Answer 20

you need to find several coordinates to plot your graph

Answer 21

x = 2 , y = 12 ( 2 , 12)
x = 3 , y = 8 (3 , 8 )
x = 4 , y = 4 ( 4 , 4 )
x = 5 , y = 0 ( 5 , 0 )

Answer 22

my diagram is not accurate... but on graph paper you will have a straight line

Answer 23

( x = 5 , y = 0 )
This means that you can buy 5 angel but 0 neon..
