- (10) There are 24 total children (18 +6). The result must be 8 children in Room A and 16 in Room B. This can be done by moving 10 children from Room A to Room B.
- (21) Amy won 4 games, Ann won 8 games, (4 more than Amy) and 9 ties. 4 + 8 + 9 = 21.
- ($1.20) Four quarters (2 hours) and two dimes (20 minutes) would be the least expensive way to cover the time period.
- (45) 1 + 3 + 5 + 7 + 9 + 0 + 2 + 4 + 6 + 8 = 45
- (2Q, 1D) Al has 60cents, Ben has 40 cents and Casey has 20 cents. Al’s 3 coins are 2 quarters and 1 dime.
