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 last t mminutes.
$0.75 + 0.25 * t
yes
equation would be
c = 0.75 + 0.25 t
The algebraic expression that models the cost of a telephone call that lasts t minutes is $0.75 + 0.25*t.
To model the cost of a telephone call that lasts t minutes, we need to multiply the number of minutes (t) by the rate of cost per minute (0.25) and add the base cost of the call ($0.75). Therefore, the algebraic expression that represents the cost of a telephone call is:
Cost = $0.75 + $0.25t
