2. 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?
use y+mx+b

Respuesta :

1st equation= 40+1x
2nd equation= 3.50x

x=matinees
40+1x=3.50x
40=2.50x
16=x
It would take 16 times to break even. 17 times would benefit his father.

It will take "16" times to break even. "17" times would benefit his father.

According to the question,

The cost of movies pass,

  • = $40

Matinee cost with pass,

  • = $1

Normal matinee cost,

  • = $3.50

Let,

The number of times Seth attend the matinee will be "x".

then,

→  [tex]40+1x = 3.50 x[/tex]

→ [tex]3.5 x-x =40[/tex]

→        [tex]2.5x=40[/tex]

→             [tex]x = \frac{40}{2.5}[/tex]

→                [tex]= 16[/tex]  

Thus the above response is correct.
