Before you worry about phrasing the question I should have a look at the figures.
Do you mean that if one matinee and one regular ticket is sold then two student tickets are sold? If so then the total tickets sold will be 525 matinee and regular and 1,050 students. These will cost Php420,000. To make the total proceeds Php437,500 you will have to sell 546.875 matinee and regular tickets and 1,093.75 student tickets - a total of 2187.5 tickets. That's if I'm reading the question correctly.
