There are several ways that can help someone recover after they are injured. After the injury occurs, it is best to go to the doctor or hospital to get the injury, if need be, checked on or fixed. Another thing that can help is if the person rests and does not do any heavy-lifting or do to many activities that can strain the injury. After an injury occurs, if you do not rest there is more of a likelihood that you can damage it more and also rest helps the body heal. There are also several medicine's that are meant to help relieve pain after an injury occurs.

Hope it helps.

Answer:

20 months
$5500

Step-by-step explanation:

There are a couple of ways to work a problem like this. You have probably been taught to write equations for each of the payment amounts as a function of time, then equate those values to solve for the time that makes them equal.

at dealer 1, the total amount paid (y) will be a function of months (x):

y = 2500 +150x

at dealer 2, the corresponding equation is ...

y = 3000 +125x

These are equal when ...

y = y

2500 +150x = 3000 +125x

25x = 500 . . . . . . . . . subtract 125x +2500 from both sides

x = 500/25 = 20

The total paid will be the same after 20 months.

That amount is ...

y = 2500 +150(20) = 5500

$5500 will be paid to either dealer after 20 months.

The other way to work the problem is to "cut to the chase". The difference in down payment is made up at the rate of difference in monthly payments. So The number of monthly payments (x) required to equal the difference in down payments is ...

25x = 500 . . . . . . . . . you may recognize this equation from above

x = 500/25 = 20
