2000 tickets were sold to a car show on Saturday. The cost of a ticket for an adult is $4 and thecost for a child is $2. The total amount of money collected was $6400. Find the number of adult
tickets and child tickets sold.
let's assign variables
Adults= A Children=C
We know that an adult cost 4$ so 4A
We know a kid cost 2$ so 2C
We know that 2C+4A= 6400
We know that there are A number of adults and C number of children
So, we know C+A= 2000
multiply it by two so that we can subtract the two equations.
We can subtract these two equations.
Plug it into either of the equations
1200 Adults and 800 children
