Final answer:
The unit for the amount of money Alfred raised compared to the minimum is not given. An expression can be written to represent the amount of money Alfred raised based on the number of tickets sold. After the first week, Alfred raised $50.
Step-by-step explanation:
The unit for the amount of money Alfred raised compared to the minimum required depends on the unit used for the number of tickets he sells. Let's represent the number of tickets Alfred sells as 'x'.
To write an expression for the amount of money Alfred raised compared to the minimum required, we can multiply the price per ticket by the number of tickets sold. The price per ticket is not given in the question, so we cannot determine the exact amount. However, let's assume a hypothetical price of $10 per ticket. The expression would then be: 10 * x. This represents the amount of money raised by selling 'x' tickets.
After the first week, Alfred has sold 5 tickets. We can substitute 'x' with 5 in the expression: 10 * 5 = $50. Therefore, the amount of money Alfred raised after the first week is $50.
