Kay is trying to decide between two health clubs. Company A charges a one-time fee of $70 and $35 a month. Company B charges a one-time fee of $10 and $40 a month. Kay wrote two equations to represent the cost of each plan, C, after m months as shown below.
C = 35m + 70
C = 40m + 10
When Kay graphed the equations on her graphing calculator, the lines intersected at the point (12, 490). What does the point mean in relation to the scenario above?
answer choices :
After 12 months, Kay will have 490 points at the club.
After 12 people buy memberships, the club will earn $490.
After 12 months, both plans will cost $490.
After Kay spends $490, she will get 12 months free.
