It costs $100 to join a fitness center plus a monthly fee. you spent $700 last year at the fitness center. how much was the monthly fee? write and solve an equation to determine the monthly fee.

Monthly fee of fitness center is $50.

Step-by-step explanation:

Joining fee of a fitness center is $100 with a monthly fee.

I have spent total of $700 last year at fitness center and we have to calculate the monthly fee.

Let the monthly fee of the fitness center is $x.

Therefore yearly fees of the center will be = $12x

In addition to this fee i have to give the joining fee of $100. Therefore total expenditure will be = 12x + 100

Therefore the equation which represents the annual expense of the fitness center is

12x + 100 = 700

From this equation we can calculate the monthly fee.

12x = 700 - 100

12x = 600

x = 600/12 = 50

Therefore monthly fees of the fitness center is $50.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
