Answer:
[tex]p = \{x \ | \ x \in Q^+ \ and \ x \leq \$5,000 \}[/tex]
Step-by-step explanation:
The expression for the cost of John's bike (p) using set notation can written as follows;
We note that the cost of the bike is a member of the positive rational number and the cost price of the bike cannot exceed $5,000, therefore, it is less than or equal to $5,000, therefore, we get the following set notation;
[tex]p = \{x \ | \ x \in Q^+ \ and \ x \leq \$5,000 \}[/tex]
