Question

Nic has $9 to spend on cards. She finds friends with the same amount of money to split the cost of a set. One set costs $27. Each friend gets the same number of cards. How many cards does each friend get?

Answer 1

Each friend gets
`(x)/(3)` cards

Solution:

Let the number of cards in $ 27 set be "x"

Given that Nicole has $9 to spend on cards

Amount with Nicole to spend on cards = $ 9

One set costs $27

Therefore, cost of 1 set = $ 27

Each friend gets the same number of cards

She finds friends with the same amount of money to split the cost of a set

Therefore, to get total cost of 1 set which is $ 27 , we can say

$ 9 + $ 9 + $ 9 = $ 27

So 2 friends pay each $ 9 and nicole pays $ 9

Now, Number of cards each friend gets is given by

`\text{ number of cards } = \frac{\text{ total number of cards }}{\text{ 3 people}} = (x)/(3)`

Thus each friend gets
`(x)/(3)` cards
