Answer:

[tex]Sister \leq 28[/tex]

Given

[tex]Total = 50[/tex] --- at most

[tex]Damien = 10[/tex]

[tex]Discard\ Pile = 12[/tex]

Required

Represents the card with his sister as an inequality.

At any given time, the relationship between number of cards is:

[tex]Damien + Discard\ Pile + Sister \leq Total[/tex]

Where [tex]\leq[/tex] represents at most

Substitute values in [tex]Damien + Discard\ Pile + Sister \leq Total[/tex]

[tex]10 + 12 + Sister \leq 50[/tex]

[tex]22 + Sister \leq 50[/tex]

Collect Like Terms

[tex]Sister \leq 50 - 22[/tex]

[tex]Sister \leq 28[/tex]

The inequality shows that her sister could have at most 28 cards.

Because of this, Damien's belief is correct.

Answer:

Damien is correct, it is possible

Step-by-step explanation:

This is possible, here is why. Damien has 10 cards in his hand. Do 10 - 50. You get 40. There are 12 cards in the pile. Do 12-40 and then you get 28. So yes, this is possible. Damien is correct!
