so if he saves 2.50 dollars on every mantis and his  father spent 40 dollars then you dived 40 by 2.50 and get 16. he has to buy 16 mantis to earn profit . if I read the problem wrong sorry... 

Answer: He must attend 17 times  to benefit his father to buy the pass.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • Cost of the movie pass: $40
  • Matinee price: $3.50 each
  • Matinee price (with pass) : $1 each

So, we have to write an equation for the price with pass and another equation for the price with no pass. Assuming that the number of matinees is x.

  • With pass: 4+1x
  • No pass: 3.50x

If we equal the costs:  

40+ 1 x = 3.50 x

40 =3.50x -1x

40= 2.50x

40/2.50 =x

16=x

if he attends 16 times the cost will be the same for both cases.

He must attend 17 times to benefit his father to buy the pass.
