Juliette bought a number of tickets to see a rock band. Each ticket costs $45. Write an algebraic expression that represents the total cost of tickets.
45x
Is this the expression
Yes.
45 times an unknown number is 45x
To write an algebraic expression that represents the total cost of tickets, we can start by defining a variable. Let's use the variable 'x' to represent the number of tickets Juliette bought.
Now, we know that each ticket costs $45. So, the cost of 'x' tickets would be '45x' dollars.
Therefore, the algebraic expression that represents the total cost of tickets is '45x'.
