Answer:

Option B. start fraction, 2, divided by, x, end fraction, equals, start fraction, 3, divided by, dollar sign, 2, point, 91, end fraction

Step-by-step explanation:

<u><em>The correct question is</em></u>

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

\frac{2}{x}=\frac{3}{2.91}

solve for x

3x=2(2.91)

x=\$1.94

therefore

The cost of 2 folders is $1.94
