At silver gym, membership is $20 per month, and personal training sessions are $25 each. at fit factor, membership is $70 per month, and personal training sessions are $15 each. in one month, how many personal training sessions would sarah have to buy to make the total cost at the two gyms equal?

8 personal training sessions

Step-by-step explanation:

Simply add up the training session prices until they are equal;

Silver Gym: 25 + 25 + 25 = $75

Fit Factor: 15 + 15 + 15 + 15 + 15 = $75

So she needs to purchase 3 Silver Gym personal training sessions and 5 Fit Factor personal training sessions for the total cost at the two gyms to be equal.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
