Mario and Pete are playing a card game where it is possible to have a negative score.Pete's score is s and Mario's scare is s - 220.

Instructions: Write in words each given algebraic expressions.Describe a possible domain for this variable.

The given algebraic expressions are:

1) Pete's score: s
2) Mario's score: s - 220

In words:
1) Pete's score is represented by the variable "s".
2) Mario's score is represented by the variable "s" minus 220.

Domain of the variable "s":
The domain for the variable "s" in this context depends on the rules of the card game. However, since it is mentioned that it is possible to have a negative score, the domain for "s" could be all real numbers or integers (-∞, +∞). This allows for the possibility of negative scores as well.
