Answer:

350 - 170 - 120 = r

Step-by-step explanation:

Identify the variable:

r = number of red pens

The total amount of pens ordered is 350 when adding all three colors of pens. This means we must add all of the colored pens to find the total number of pens, 350.

Write this as an equation:

170 + 120 + r = 350

Rewrite the equation to find r:

350 - 170 - 120 = r

Fudgin [204]

Answer:

The equation modelling the situation is T=200+20m.

After <u>10 months</u> 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;

T=200+20m

Hence The equation modelling the situation is T=200+20m.

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.

200+20m=400

Subtracting both side by 200 we get;

200+20m-200=400-200\\\\20m=200

Dividing both side by 20 we get;

\frac{20m}{20}=\frac{200}{20}\\\\m=10 \ months

Hence After <u>10 months</u> the cost would be $400.
