Seth's father is thinking of buying his son a six-month movie pass for $40. With the pass matinees cost $1.00. If matinees are normally $3.50 each, how many times must Seth attend in order for it to benefit his father to buy the pass?
If mantinees cost 3.50,
but you only pay 1.00,
then you subtract...
3.50 - 1.00 = 2.50
to get amount saved per mantanee.
With that number we divide it out throught 40
40/2.5 = 16.
It would take 16 mantinees purchased until he's saved as much money as he paid.
