Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Lola just became a personal trainer and is finalizing her pricing plans. One plan is to charge $17 for the initial consultation and then $38 per session. Another plan is to charge $19 for the consultation and $36 per session. Lola realizes that the two plans have the same cost for a certain number of sessions. How many sessions is that? What is that cost?For _____ sessions, the cost is $_____ on either plan.
Q. Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Lola just became a personal trainer and is finalizing her pricing plans. One plan is to charge $17 for the initial consultation and then $38 per session. Another plan is to charge $19 for the consultation and $36 per session. Lola realizes that the two plans have the same cost for a certain number of sessions. How many sessions is that? What is that cost?For _____ sessions, the cost is $_____ on either plan.
Define variables: Let's define the variables for the number of sessions as n and the total cost for each plan as C. We can write two equations to represent each plan:Plan 1: C=17+38nPlan 2: C=19+36nWe are looking for the number of sessions n where the cost C is the same for both plans.
Use substitution to solve: To solve for n, we can use substitution by setting the two equations equal to each other since they both equal C at the point where the plans cost the same.17+38n=19+36n
Subtract to isolate variable: Now, we will solve for n by subtracting 36n from both sides of the equation:17+38n−36n=19+36n−36n17+2n=19
Divide to solve for n: Next, we subtract 17 from both sides to isolate the variable 'n':17+2n−17=19−172n=2
Substitute n back in equation: Now, we divide both sides by 2 to solve for 'n':22n=22n=1
Calculate total cost: We have found that the number of sessions 'n' where the cost is the same for both plans is 1. Now we need to find out what that cost is. We can substitute 'n' back into either of the original equations. Let's use Plan 1:C=17+38nC=17+38(1)
Calculate total cost: We have found that the number of sessions 'n' where the cost is the same for both plans is 1. Now we need to find out what that cost is. We can substitute 'n' back into either of the original equations. Let's use Plan 1:C=17+38nC=17+38(1)Now, we calculate the total cost 'C' for 1 session:C=17+38C=55
