Answer:
1) $68.40
2)456 tickets
Step-by-step explanation:
1)
They need to raise $8,250.
They have already raised $3,120.
The amount they have still to raise is $8,250-$3,120=$5,130.
There are 75 band members, so the amount yet to raise per member is $5,130/75=$68.40.
2)
The businesses give $0.50 for every $1 in ticket sales, ie. they pay an extra 50% of the total.
Let number of tickets sold=x
Let money made from ticket sales = 7.5x
The total amount of money made is therefore 1.5(7.5x)=11.25x
The minimum amount of tickets to hit $5,130:
$5,130=11.25x
x=456
