a 20-ounce bag of popcorn costs $2.80. if the unit price stays the same, how much does a 35-ounce bag of popcorn cost?

6 answers

20/2.80 = 35/x

Cross multiply and solve for x.
$2.80/20 = x/35

Divide $2.80 by 20 and multiply by 35.
20/2.80=35/x
20x=35*2.80
20x=98
divided by 20 on both sides
x=4.90?
Right.
