Question

The graph above shows the total cost of goldfish at the aquarium shop. Use a table to find out how much 5 goldfish cost.

Answer 1

seems to be 2 fish=4 dollars, 4 fish is 8 dollars

hmm, we notice that for x fish, it costs 2x dollars

so for 5 fish, it costs 2 times 5 or 10 dollars

costs 10 dollars
we can also just draw a line through the points and see it intersects fish=5 at dollars=10


10 dollars for 5 fish

Answer 2

5 goldfish cost $10 dollars.

----------------------

This question is solved using proportions.

From the graph, we have that:

• 1 goldfish costs $2.
• 2 goldfish cost $4.
• 3 goldfish cost $6.
• 4 goldfish cost $8.

From this, it can be found that each goldfish costs $2, so 5 goldfish will cost 5*$2 = $10.
