A group of tourists went to Sentosa. The total fare is $240. If 10 more tourists join the tour each will pay $4 less. Find the original number of tourists in the group

  • Calculus -

    If there are n tourists, the cost each is 240/n

    240/n - 4 = 240/(n+10)
    n=20

    check:
    240/20 = 12
    240/30 = 8 = 12-4
