5 squirrels collected 575 acorns. If each squirrel needs 130 acorns to get through the winter, how many more acorns does each squirrel need to collect?
Each squirrel now has 575/5 = <T>divide(575, 5)=115.0 acorns.
Each squirrel still needs to collect another 130 - 115 = <T>subtract(130, 115)=15 acorns.
