Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $9 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has a $16 monthly fee and charges an additional $0.09 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal

the number of minutes of call when the two cost plans would be equivalent to each other is 175 minutes

Step-by-step explanation:

The computation of the number of minutes of call when the two cost plans would be equivalent to each other is shown below:

Let us assume the number of minutes be x

Now the equation is

$9 + 0.13x = $16 + $0.09x

0.13x - 0.09x = $16 - $9

0.04x = $7

x = $7 ÷ 0.04

= 175 minutes

Hence, the number of minutes of call when the two cost plans would be equivalent to each other is 175 minutes

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
