Marissa has budgeted $65 for her monthly cell phone expense. If her plan with her wireless provider is $15 plus $0.25 for each minute, how many minutes can she talk on her cell phone in a month and not exceed her budget?
65 - 15 = 50
50 / 0.25 = ?
200
Right. She can talk for 200 minutes.
thank you I had that when I was trying to solve the problem just wanted to make sure it was right.
To find out how many minutes Marissa can talk on her cell phone without exceeding her budget, we need to set up an equation.
Let's assume Marissa talks for 'm' minutes.
The total cost of her cell phone plan is $15 plus $0.25 for each minute, which can be written as:
Total cost = $15 + $0.25*m
We want to find the maximum value of 'm' that will not exceed her budget of $65.
So, we can set up the following equation:
$15 + $0.25*m ≤ $65
To solve for 'm', we need to isolate it on one side of the equation:
$0.25*m ≤ $65 - $15
$0.25*m ≤ $50
Next, we can divide both sides of the inequality by $0.25 to solve for 'm':
m ≤ $50 / $0.25
m ≤ 200
Therefore, Marissa can talk on her cell phone for a maximum of 200 minutes in a month without exceeding her budget.
