Three times as many children as adults attend a concert on Saturday. An adult's ticket cost $7 and a child's ticket cost $3. The theater collected a total of $6,000. How many people bought tickets?

  • Math -

    Let
    a=number of adults
    then
    3a=number of children
    Total revenue, $6000
    =7a+3(3a)
    =16a

    a=6000/16=375 (number of adults)
    3a = 375*3 = 1125 (number of children)

    Check:
    7*375+1125*3=$6000 OK
