To find out how much more money needs to be raised per band member, follow these steps:
-
Calculate how much money still needs to be raised: \[ \text{Total Amount Needed} - \text{Amount Raised} = \text{Amount Still Needed} \] \[ $8,250 - $3,120 = $5,130 \]
-
Now, divide the amount still needed by the number of band members to find out how much each member needs to raise: \[ \frac{\text{Amount Still Needed}}{\text{Number of Band Members}} = \text{Amount Per Band Member} \] \[ \frac{$5,130}{75} = $68.40 \]
So, each band member still needs to raise $68.40 for the trip.
