The phone company charges a flat rate of $2.50 plus and additional $0.50 each minute for a long-distance phone call.
Write an equation to represent the total cost of making a long-distance phone call.
Let's call the total cost of making a long-distance phone call "C". We can represent the equation as follows:
C = 2.50 + 0.50m
Where "m" represents the number of minutes spent on the call. This equation calculates the total cost by adding the flat rate of $2.50 to the additional charge of $0.50 per minute multiplied by the number of minutes spent on the call.
To write an equation that represents the total cost of making a long-distance phone call, we need to consider two components: the flat rate and the cost per minute.
Let's start by representing the flat rate as a constant value, which is $2.50. We can denote this as "2.50".
Next, we need to consider the cost per minute, which is an additional $0.50. Since this cost varies depending on the duration of the call, we can use the symbol "m" to represent the number of minutes. Therefore, the cost per minute can be expressed as "0.50m".
To calculate the total cost, we need to add the flat rate to the cost per minute. This can be written as:
Total cost = Flat rate + Cost per minute
So, the equation to represent the total cost "C" of making a long-distance phone call would be:
C = 2.50 + 0.50m
