Alex wants to find out how many ducks there are in a park.

1 answer:

8 0

An estimate for the number of ducks would be 62.

There were 30 the first day.
The second day, 8 of those 30 were there as well, so we subtract that from the 40 ducks and get 32.
Add 30 and 32 to get our estimate.

If you would like to know what is the amount of money Yul should leave for the tip, you can calculate this using the following steps:
