OK, here we go. Golf Club first
You subtract the total amount they need to raise, by the amount they already have:
2620 - 1225 = $1395.00 to go
Divide that number by the price of golf balls to find out how many more they need:
1395/25 = 55.8
This means that they need to sell at least 56 golf balls to meet the target.
Now to the Percussion Club...
Do the same thing again:
2400 - 1314 = $1086 to go
1086/18.25 = 59.51
So the percussion club needs to sell at lest 60 more tubs of popcorn to reach their target.
Hope this helps!! :)
