A possible algebraic expression to represent the total cost of the rental is Total cost: x + yd.
In mathematics, algebraic expressions are a combination of numbers, letters, and mathematical signs (+ - x /) often used to represent a value.
Here are the steps to write this expression:
1. Identify the variables that you need to include: In the case of the tuxedo rental there are three variables or factors.
All of these variables can be expressed using letters because we do not know the exact value of each.
2. Use appropriate mathematical signs to relate the previous factors: In this case, we know the number of days should be multiplied by the rate for additional days and this should be added to the rate he initially paid.
