If chris eats cookies at a rate of 5 cookies every 2 minutes, will he finish all 19 of them in 7 minutes before his parents come home?

no

Step-by-step explanation:

Chris' Ratio/Rate : 5cookies:2minutes

Find the unit rate: cookies per minute

5/2=2.5

Chris eats 2.5 cookies per minute

Now, to find out if he would finish all 19 of them in 7 minutes, multiply 2.5 by 7.

2.5 x 7 = 17.5

So the answer would be No, Chris could not finish all of the cookies in time.

he would have 1.5 cookies left over

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
