Let’s check out your problem:

Reggie just became a personal trainer and is finalizing his pricing plans. One plan is to charge $30\$30 for the initial consultation and then $35\$35 per session. Another plan is to charge $40\$40 for the consultation and $30\$30 per session. Reggie realizes that the two plans have the same cost for a certain number of sessions. How many sessions is that?\newlineWrite a system of equations, graph them, and type the solution.\newline____\_\_\_\_ sessions\newline

Q. Reggie just became a personal trainer and is finalizing his pricing plans. One plan is to charge $30\$30 for the initial consultation and then $35\$35 per session. Another plan is to charge $40\$40 for the consultation and $30\$30 per session. Reggie realizes that the two plans have the same cost for a certain number of sessions. How many sessions is that?\newlineWrite a system of equations, graph them, and type the solution.\newline____\_\_\_\_ sessions\newline
  1. Define Total Cost: Let's define the total cost for each plan based on the number of sessions, xx. For the first plan, the cost is $30\$30 for the consultation plus $35\$35 per session. So, the equation is 30+35x30 + 35x. For the second plan, it's $40\$40 for the consultation plus $30\$30 per session, giving us the equation 40+30x40 + 30x.
  2. Set Equations Equal: Now, we set the equations equal to each other to find when the costs are the same: 30+35x=40+30x30 + 35x = 40 + 30x.
  3. Subtract and Simplify: Subtract 30x30x from both sides to get 35x30x=403035x - 30x = 40 - 30, simplifying to 5x=105x = 10.
  4. Divide and Solve: Divide both sides by 55 to solve for xx: x=105x = \frac{10}{5}, which simplifies to x=2x = 2.
