Answer 12

Okay, so we want to divide the number of minutes by the number of items to get items per minute. So, 36 minutes/20 items = ?

Answer 13

1.8

Answer 14

Correct. So, we now know that she does 1 problem in 1.8 minutes. Let's Now multiply the number of items for Wednesday's homework by 1.8 minutes because she worked at the same rate for both day.

So, 1.8*35=?

Answer 15

63 thanks

Answer 16

You're welcome.

And 63/1.8=35 just to check our work.


Have a nice day!

Answer 17

35 minutes not 63?

Answer 18

No, its 63. The 35 was just working backwards to check our work. Sorry for the confusion. But 63 is the answer

Answer 19

OKay thanks
