Question 1077631: Below is what I have so far:
A basketball team sells tickets that cost $10, $20, or, for VIP seats, $30. The team has sold 3343 tickets overall. It has sold 113 more $20 tickets than $10 tickets. The total sales for $62,350. How many tickets have been sold?
How many $10 tickets were sold?
How many $20 tickets were sold?
How many $30 tickets were sold?
I have been able to figure out:
3343 tickets overall
113 more $20 tickets than $10 tickets
62,350 total sales
$10 = a
$20 = b
$30 = c
a + b + c = 3343
b = a + 113
10a + 20b + 30c = 62350
This is where I am stuck:
a+2b+3c= (should this be 140)?
What do I need to do from here, specifically, in order to get the three ticket sold amounts? Please be specific in your steps.
