Answer 1

To solve this problem, we have to determine the 34.4% of 20. To find the x% of y, we can use the following expression:

`y*(x)/(100).`

Therefore, the 34.4% of 20 is:

`20*(34.4)/(100)=6.88.`

Subtracting the above amount from20, we get:

`20-6.88=13.12.`

Answer:

The cheese bill decreased this week by

`6.88\text{ dollars.}`

The total cheese bill for this week is:

`13.12\text{ dollars.}`
