The number of candy canes at first is the same for Case 1 and 2.
The number of caramel apples at first is also the same for Case 1 and 2.
1 u = 2 p + 29 --- (1)
1 u + 20 = 3 p
1 u = 3 p - 20 --- (2)
(2) = (1)
3 p - 20 = 2 p + 29
3 p - 2 p = 29 + 20
1 p = 49
Total number of candy canes and caramel apples
= (2 p + 29) + 3 p
= 5 p + 29
= 5 x 49 + 29
= 245 + 29
= 274
Answer(s): 274
