The number of lollipops 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 = 5 p + 11 --- (1)
1 u + 13 = 6 p
1 u = 6 p - 13 --- (2)
(2) = (1)
6 p - 13 = 5 p + 11
6 p - 5 p = 11 + 13
1 p = 24
Total number of lollipops and caramel apples
= (5 p + 11) + 6 p
= 11 p + 11
= 11 x 24 + 11
= 264 + 11
= 275
Answer(s): 275
