Answer:
The band needs to sell 4 more items from their fundrasier than the chorus needs to sell for their fundraiser.
Explanation:
First we have to see how far each of the groups are from completing their goal.
For chorus, we get 2620-1225=1395 dollars.
For band, we get 2400-1314=1086 dollars.
Now, we see how long it takes for them to get to their goals.
For chorus, we get 1395/25 = 55.8. because they can't sell 0.8 of a set of candles, it round up to 56 candles.
For band, we get 1086/18.25 ≈ 59.5. because they can't sell half of a 3 gallon tubs of caramel popcorn, they have to sell 60.
So, when both of the funraisers meet their goals, the band needs to sell 4 more items from their fundrasier than the chorus needs to sell for their fundraiser.
