Student budgeted a $25 a month for phone service. If the telephone company charges $18 a month for basic service and $.05 a minute for each long distance call, how many minutes can be spent on long distance calls each month?
(25 - 18) * 0.05 = ?
35
I'm sorry -- but I goofed.
The problem should be 7 / 0.05 = 140.
He can make 140 long distance calls a month.
To find out how many minutes can be spent on long distance calls each month, we need to determine the amount of money that remains after the basic service fee of $18 is paid.
The remaining amount can be used to make long-distance calls, and since each minute costs $0.05, we can calculate the number of minutes that can be spent.
Let's break it down step by step:
1. Start with the monthly budget of $25.
2. Subtract the basic service fee of $18: $25 - $18 = $7.
3. Using the remaining amount of $7, we can calculate the number of minutes for long-distance calls by dividing it by the cost per minute:
$7 / $0.05 = 140 minutes.
Therefore, the student can spend up to 140 minutes on long distance calls each month within their budget.
