McKenzie's work is correct because on step 3 she added the A and the B correctly.
Answer:
y=6x+25
Step-by-step explanation:
y will be the whole cost. 6 is how many sessions you have and x is the cost of each of those sessions. The one time introduction fee is 25. you would add 25 plus 6 times the cost of sessions (x) and you would get your answer (y).
X= 36 I think
Hope this helps
6>y , i don’t get the other one cuz it would just be y+(a number)
