Problema Solution
On family day, attendance at the baseball game set a record. A reporter for the local paper asked how many adults happy to see the game. The box office reported that exactly 450 tickets had been sold, and $2000 was collected. If adults tickets were five dollars and children's tickets were three dollars, how many adults tickets were sold?
Answer provided by our tutors
let
a = the number of adult's tickets sold by the cost of $5 per ticket
c = the number of children's tickets sold by the cost of $3 per ticket
the box office reported that exactly 450 tickets had been sold, and
a + c = 450
$2000 was collected
5a + 3c = 2000
by solving the system of equations
a + c = 450
5a + 3c = 2000
we find
a = 325 adult's tickets sold
c = 125 children's tickets sold
