Explanation:

The correct question is

3 folders cost $2.91 which equation would help determine the cost of 2 folders

we know that

3 folders cost $2.91

so

by proportion

Determine the cost of 2 folders

Let

x ----> the cost of 2 folders

`(2)/(x)=(3)/(2.91)`

`3x=2(2.91)`

`x=\$1.94`

therefore

The cost of 2 folders is $1.94
