So, the answer is 4 dollars.

You can find price of 1 ounce of cheese, then find cost of 20 ounces of cheese by simply using multiplication.
The cost for 20 ounces of cheese is $4.00
Given that:
- The cost for 16 ounces of cheese is $3.20
To find:
Cost for 20 ounces of cheese
Finding cost of 1 ounce of cheese:
[tex]16 \: \rm ounce = \$3.20\\\\\\ \text{Dividing by 16 on both sides}\\\\ 1 \rm \: ounce = \dfrac{3.20}{16} = \$0.2[/tex]
Finding cost of 20 ounces of cheese:
Multiplying both sides of above equation by 20, we get:
[tex]1 \rm \: ounce = \dfrac{3.20}{16} = \$0.2\\ \\ 20 \times 1 \rm \: ounce = 20 \times \$0.2\\ 20 \text{\:ounce of cheese \:}= \$4[/tex]
