Answer 1

The butter for one portion cost is $0.35.

Explanation:

Given : You buy butter for $3.31 a pound. One portion of the onion compote requires 1.7 oz of butter.

To find : How much does the butter for one portion cost?

Solution :

First we need to convert pounds to ounces,

1 pound = 16 ounces

i.e. 16 ounce cost $3.3.

1 ounce cost
`(3.3)/(16)`

One portion of the onion compote requires 1.7 oz of butter.

So, 1.7 ounce cost
`(3.3)/(16)* 1.7`

1.7 ounce cost $0.350625.

Rounding to the nearest cent - $0.35.

Therefore, the butter for one portion cost is $0.35.
