Gym A has an membership fee of $100 and a monthly
cost of $30. Gym B has a
membership fee of $70 and a
monthly cost of $40. How
many months until both cost
the same?

3months

Step-by-step explanation:

130 160 190 220 250 280 310 340 370 400

110 150 190 230 270 310 350 390 430 470 510

After 3 months they will both be at 190

3 months until both costs are the same

Step-by-step explanation:

30x+100 = 40x+70

-30             -30

        100  = 10x+70

       -70              -70

        30 = 10x

     30/10   10x/10    

      30/10 = 3

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

it would be 6xy and -16xy.
