  1. Use a proportion. Cross multiply and solve for x.

    20/2.80 = 35/x

  2. -First find the cost per ounce:
    2.80 divided by 20 = .14 per ounce
    -Then, multiply by 35 to find the price for 35 ounces:
    .14 x 35 = 4.90
    -Therefore, a 35 ounce bag of popcorn would be $4.90!
    Hope this helped!
