Question

3 folders cost $2.91

what is which equation would help determine the cost of 2 folders?

Answer 1

The cost of two folder is $ 1.94

Solution:

Given that 3 folders cost $ 2.91

We have to determine the cost of 2 folder

From given,

Cost of 3 folder = $ 2.91

To find the cost of 1 folder, divide 2.91 by 3

$Cost\ of\ one\ folder = \frac{2.91}{3} = 0.97$

Thus cost of 1 folder is $ 0.97

We are asked to find cost of two folders.

Therefore, multiply cost of 1 folder by 2

$Cost\ of\ two\ folder = 2 \times Cost\ of\ one\ folder\\\\Cost\ of\ two\ folder = 2 \times 0.97\\\\Cost\ of\ two\ folder = 1.94$

Thus cost of two folder is $ 1.94
