A volume of 10 ounces of popcorn was $6 and a volume of 20 ounces cost$8

So, for every 10 ounces increase there is an increase of $2. If there is a 5 ounce increase there is an increase of \frac{5 \cdot 2}{10} = 1 dollar. 35 ounces is a 10 ounce + 5 ounce increase so it cost$2 + $1 =$3, extra so $8 +$3 = $11. Since extra 10 ounces cost$2,

3 ounces cost \frac{3\cdot 2}{10} =0.6 dollars.

48 ounces = 45 ounces + 3 ounces = $13 +$ 0.6 = $13.6 60 ounces is 58 ounces + 2 ounces 58 ounces is a 10 ounce increase over 48 so it costs$13.6+ $2 =$15.6.

We know that 10 ounces cost $2 extra 2 ounces will cost \frac{2 \cdot 2}{10} = \frac{4}{10} = 0.4 dollars extra 60 ounces = 58 ounces + 2 ounces =$15.6 + $0.4 =$16.
