Answer:
4 personal training sessions
Step-by-step explanation:
You would first create 2 expressions, one to represent each situation
Silver Gym: 25 + 30x
Fit Factor: 65 + 20x
Then if you want to find when the costs would equal each other, set them equal to each other.
25 + 30x = 65 + 20x
Then solve:
25 + 30x - 20x = 65 + 20x - 20x
25 + 10x = 65
25 - 25 + 10x = 65 -25
10x = 40
10x / 10 = 40 / 10
x = 4
She will have to attend 4 personal training sessions to make the total cost at the two gyms equal.
This means the answer is off topic or way off point
C and b , both can be a number multiplied by 10 to the power of -6
