The price for each pound of tuna is the same. Each pound costs $5. For 10 lbs of tuna, it would be $50.

Step-by-step explanation:

For these kind of questions, you can either find the pattern in the information given or you find the unit price.

Pattern: Check the numbers to see if there are any patterns happening. 3 mutlpiled by 5 gets you 15, 7 muliplied by 5 gets you 35, and 9 multipled by 5 gets you 45.

Unit Price: You would need to find the price for one item, or in this case, one pound. If 3 lbs is $15 dollars you would do 15/3, 15 divided by 3/total price divided by pounds, so you would get $5. You can also change the denominator to 1 and to do this you would divide the 3 by 3 to get 1 and what you do to the bottom, you do to the top so you also divide 15 by 3 and you would get 5. In conclusion, 5/1 which is 5 dollars for one pound.

The arrows represent the number it goes in btw. I'm not too good with explaining things so let me know if you need clarifications on anything and I also personally recommend the unit price method since it isn't easy to spot a pattern with harder questions. Tell me if I'm wrong please so I can go back and look:)
