Chip said to Dale "If you give me one acorn, then we will have an equal number of acorns." Dale replied with delight "If you give me one acorn, then I will have double the number you have!" What was the total number of acorns they had in their tree? How many did Chip have and how many did Dale have?
Chip has five and Dale has seven.
Let C = # of acorns Chip had and D = # acorns Dale had.
Then C + 1 = D - 1 ; D=! = 2(C-1).
Solve to get C = 5 and D = 7.
