Help me Now we are in zoom I finished the test so I need to do this before all my class mates finish the test

252

Step-by-step explanation:

21 times 12 i can only answer part of it

Step-by-step explanation:

A) 8 : 12

B) Yes, because 21 doesn't go evenly into 8 or 12. If you could narrow it down to 1 pound to whatever cost. It would be easier to calculate for 21 pounds of pasta.

C) 8 / 12 = .67 (0.67 cents per pound)

21 x .67 = 14 (21 pounds x 0.67 cents = total cost)

21 pounds of pasta would cost a total of 14 dollars

*edited because I accidentally put 24 instead of 14
