Lamar added 8 fish to his pond each day for 72 days. What was the total change in the number of fish in the pond?

The question asks for the Total Change in the number of fish.

So if the number of fish increases by 8 every day. And it increases 72 times then to find the answer we must say 8 x 72 .

To work this out we do the following

(8x70)+(8x2)

= 560 + 16

= 576
