Answer 1

which expression would be used

Answer 2

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 = (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 * Cost\ of\ one\ folder\\\\Cost\ of\ two\ folder = 2 * 0.97\\\\Cost\ of\ two\ folder = 1.94`

Thus cost of two folder is $ 1.94
