Two gyms offer a two-month "boot camp" training program. One gym charges $4 per session plus a one-time $50 fee. The other charges $6 per session plus a one-time $30 fee. For what number of sessions is the cost of the program the same for each gym?
To answer this item, we let x be the number of sessions at which the two rates would be equal. For gym A, the total would become, 50 + 4x while that of B is 30 + 6x Equating these two expressions, 50 + 4x = 30 + 6x The value of x from the equation is 10.
