1. A mathematical expression showing the amount Trey will owe for his car is y = 2x.
2. For an 11-day rental, the amount that Trey will owe for his car is $22.
A mathematical expression is a mathematical statement that shows the value of the expression, which is always made up of numbers, variables, constants, coefficients, and mathematical operations.
Mathematical operations include addition, subtraction, division, and multiplication.
Let the daily rental charge = $2
The number of days the car is rented = x
The total rental charge = y
y = 2x.
For an 11-day rental:
y = 2 x 11
y = 22
y = $22
Thus, the expression that shows the amount that Trey would owe for an 11-day rental is $22.
