Question

Kyle has 22 more cards than 3 times the number of cards that Stan owns. Together, they own less than 58 cards. How many cards are in Stan's collection?

Answer 1

Let

x-------> the number of cards in Kyle's collection

y------> the numbers of cards in Stan's collection

we know that

`x=22+3y` ------> equation A

`x+y < 58` ------> inequality B

using a graphing tool

see the attached figure

The solution is the triangular shaded area

the numbers of cards in Stan's collection is

`y < 9\ cards`

therefore

the answer is

the numbers of cards in Stan's collection is less than
`9\ cards`
