She starts at 10:00am.

Since she took 3hrs and 30 minutes to bake, all you have to do is go back 3 hours (10:30) then back 30 minutes (10:00)

Answer:

So you have to do this Time Wise. What I mean by this is Kelly ended at 1:30 and she took 3 hours and 30 minutes with this being said, you subtract.

(Subtract 30 from the 3 hours and 30 minutes to make the 1:30 easier to solve)

1:30 - 30 = 1:00

So know we subtract 3 hours Time Wise.

(Go hour by hour of the 3 hours you have left. You subtract 3 times because there are 3 hours )

1:00 - 1:00 = 12:00

12:00 - 1:00 = 11:00

11:00 - 1:00 = 10:00

She started at 10:00.

Your answer is: $3.15 each.

Here are the steps:

First, I added $2.82 and $1.43. Then, I subtracted the sum ($4.25) from $20. Lastly, I divided the difference($15.75) by five because there were five pineapples. Which gave me the answer: $3.15.
