Edwin is helping his dad in running a restaurant. He has a pile of 44 potatoes to peel. He is able to peel 3 potatoes per minute. After 4 minutes Jessica joints into peel at a rate of 5 potatoes per minute.

When they were finished how many potatoes did Jessica peel?

20 potatoes.

Step-by-step explanation:

- First find how many potatoes Edwin can peel by himself starting off.

To do this take 3 x 4 = 12

- Next, find how many Jessica can do. For this we will guess and check. We will try 4 also.

To do this take 4 x 5 = 20

- Now that we have 32 potatoes peeled, all we have to do is add another 4 minutes to Edwin to even the times out between him Jessica.

To do this take 3 x 4 = 12

- Now lets check our work...

12+20+12 = 44  (our answer is correct for potatoes, as one can see the 20 was Jessica)

- Hope this helps! If you need a further explanation please let me know.
