The cost of a telephone call is $0.75 + $0.25 times the number of minutes. Write an algebraic expression that models the cost of a telephone call that lasts t minutes.
The algebraic expression that models the cost of a telephone call that lasts t minutes would be:
0.75 + 0.25t
explain
The algebraic expression 0.75 + 0.25t represents the cost of a telephone call that lasts t minutes.
In the expression, 0.75 represents the initial cost of the call, which is a fixed fee regardless of the duration of the call.
The term 0.25t represents the additional cost per minute. Here, 0.25 is the cost per minute, and t is the number of minutes.
By multiplying 0.25 by the number of minutes (t), we calculate the additional cost based on the length of the call.
Adding the fixed cost (0.75) to the additional cost (0.25t) gives the total cost of the call.
For example, if a call lasts 10 minutes, the expression evaluates to:
0.75 + 0.25(10) = 0.75 + 2.5 = 3.25
Therefore, the cost of a 10-minute call would be $3.25.
so what should i put down?
You should put down the expression:
0.75 + 0.25t
