Question #93dbf

Answer 1

Cost of folder = x= $0.305
Cost of notepad = y = $2.34

Explanation:

Let us call the cost of each folder $x and cost of each notepad $y.
This allows us to form two equations which we can solve and get the answer.

Equation 1:
`8x + 4y = 11.80` (Cost of 8 folders =`8x` and cost of 4 notepads =`4y`)

Equation 2:
`12x + 5y = 15.41`(Cost of 12 folders =`12x` and cost of 5 notepads =`5y`)

Multiplying Eq.1 by `3` and Eq.2 by `2`
`24x + 12y = 35.40`
`24x + 10y = 30.82`

Subtracting the equations give :
`2y = 4.68"`

`y=2.34`

Substituting the value in Eq1.,
`8x + 9.36 = 11.80`

`x=0.305`

Answer:
Cost of folder = x= $0.305
Cost of notepad = y = $2.34
