At silver gym membership is $25 per month, and personal training sessions are $30 each. at fit factor, membership is $65 per month, and personal tranning sessions $20 each. in one month how many personal training sessions would sarah have to buy to make the total cost at two gyms equal?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

7.3

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
