Health club a charges 100.00 membership fee plus 25.00 per plus 25.00 per month
health club b charges a 200.00 membership fee plus 20.00 per month. for what number of months are the health club costs the same?

Month 5 the cost will be the same

Step-by-step explanation:

Make to equations from the given information

Let y be the cost, and let x be the number of months

Club A:  y = 25x + 100

Club B:  y = 20x + 200

It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..

25x + 100 = 20x + 200

5x = 100              (subtract 20x and 100 from both sides)

  x = 20                (divide both sides by 5)

So after 5 months the cost will be equal,

yes. we do proportions in probabilities.

hello! just here for points! though i wish i knew!
