Given : 75 band members need to raise a total of $8,250 for a trip. So far, they have raised $3,120.
To Find : How much money, in dollars, per band member, still needs to be raised for the trip
Solution:
need to raise a total of $8,250
already raised $3,120.
Need to raise more = 8250 - 3120
= 5130 $
Number of members = 75
Per member = 5130/75 = 68.4 $
Tickets for the concert will cost $7.50 each
$0.50 for each $1.00 in ticket
=> (0.5/1) * 7.50 = 3.75 $ per ticket
Hence earning from 1 ticket = 7.5 + 3.75 = 11.25$
tickets the band must sell = 5130 /11.25
= 456
