Answer 1

It would cost $174.

You can write the equation like this:

4/116=6/x

Steps:

1. cross multiply: 116 times 6, which is 696
2. divide: 696 divided by 4 is 174

x is 174.

Answer 2

6 ounces would cost $174.
Each ounce costs (116/4), or 29 dollars.
6 ounces at a rate of 29 dollars per ounce is 174.
