The cost of a telephone call is zero. 75+0. 25 times a number of minutes right in algebra expression that models the cost of the telephone call that last T minutes
To create an algebraic expression that models the cost of a telephone call that lasts T minutes, you need to consider that there is a fixed cost and a variable cost depending on the number of minutes.
In this case, the fixed cost is zero, so it doesn't contribute to the total cost of the call. The variable cost is $0.25 for each minute of the call. So, for T minutes, the variable cost would be $0.25 multiplied by T.
The algebraic expression that models the cost of the telephone call that lasts T minutes can be written as:
0.25T
