Company A charges $11 per month plus $0.05 per minute, while company B charges $0.15 per minute with no monthly charge. For how many minutes will the monthly cost be the same??
solve:
15m = 5m + 1100
To determine the number of minutes for which the monthly cost is the same for both companies, we need to set up an equation.
Let's assume that the number of minutes is represented by "x".
For Company A, the monthly cost is given by:
Cost_A = $11 (monthly charge) + $0.05 (cost per minute) * x (number of minutes)
For Company B, the monthly cost is given by:
Cost_B = $0.15 (cost per minute) * x (number of minutes)
Setting these two costs equal to each other, we can form an equation:
$11 + $0.05x = $0.15x
Now, we can solve for x:
Subtracting $0.05x from both sides:
$11 = $0.10x
Dividing both sides by $0.10:
$11 / $0.10 = x
Simplifying:
110 = x
Therefore, the monthly cost will be the same for both companies when the number of minutes is 110.
