Answer:total amount that was was collected is $8500
Explanation:
Let x represent the total number of floor seats sold.
Let y represent the total number of VIP seats sold.
The total number of tickets sold for the fund raising concert was 500. This means that
x + y = 500
Four times as many floor seats were sold than VIP seats. It means that
x = 4y
Substituting x = 4y into x + y = 500, it becomes
4y + y = 500
5y = 500
y = 500/5 = 100
x = 4y = 4 × 100
x = 400
If each floor seat ticket sold for $10 and each VIP ticket sold for $45, the total money collected would be
10 × 400 + 45 × 100 = 4000 + 4500
= $8500
