In order to join a flying club,there is a $200 annual fee and $20 a month fee to maintain the flying club runaway.Write an equation to model this situation. After how many months will the cost be $400

Respuesta :

Answer:

The equation modelling the situation is [tex]T=200+20m[/tex].

After 10 months the cost would be $400.

Step-by-step explanation:

Given:

Annual Fee of flying club = $200

Monthly fee = $20

We need to write an equation for total cost.

Solution:

Let the number of months be denoted 'm'

Let Total cost be denoted by 'T'

Now we can say that:

Total cost is equal to sum of Annual Fee of flying club plus Monthly fee multiplied by number of months.

framing in equation form we get;

[tex]T=200+20m[/tex]

Hence The equation modelling the situation is [tex]T=200+20m[/tex].

Now given:

We need to find the number of months when total cost will be $400

So we will substitute T= 400 in above equation.

[tex]200+20m=400[/tex]

Subtracting both side by 200 we get;

[tex]200+20m-200=400-200\\\\20m=200[/tex]

Dividing both side by 20 we get;

[tex]\frac{20m}{20}=\frac{200}{20}\\\\m=10 \ months[/tex]

Hence After 10 months the cost would be $400.
