Question

In two or more complete sentences explain how you would set up and solve the equation: Dan and Rick belong to different gyms. Dan’s gym charges $40 per
month and $15 per private training class and Rick’s gym charges $70 per month and $5 per private training class. After how many private training classes will they have paid the same amount for their gym membership?

Answer 1

The equation would be 40+15p=70+5p. You would subtract 5p from each side (15-5) and (5-5) and you'll have 40+10p=70. You would then subtract 40 from each side (70-40) and (40-40) to have 10p=30. You would divide by both of the sides by 10, you would end up with p=3. P is price training. The reason you divide and subtract on both sides is because you want the months to be on one side and the price training on the other side.
