3 folders cost $2.91 which equation would help determine the cost of 2 folders
eimsori [14]

Answer:

The equation that will determine the cost of two folders is;  3x = 2× $2.91

and  the cost of  the 2 folders is $1.94

Step-by-step explanation:

To solve this problem, we will follow the steps below;

Using proportion;

Let x be the cost of 2 folders

3 folders = $2.91

2 folders  =  x

Cross-multiply

3x = 2× $2.91

The equation that will determine the cost of two folders is

3x = 2× $2.91

We can go ahead and solve

3x = $5.82

Divide both-side of the equation by 3

\frac{3x}{3}  =  \frac{5.82}{3}

x = $ 1.94

The cost of 2 folders is $1.94
