Total number of chocolate bars
= 9 u + 5 u + 1 u
= 15 u
Number of chocolate bars that each had in the end
= 15 u ÷ 3
= 5 u
Number of chocolate bars that Kylie gave to Roshel and Penelope
= 9 u - 5 u
= 4 u
4 u = 52
1 u = 52 ÷ 4 = 13
Total number of chocolate bars
= 15 u
= 15 x 13
= 195
Answer(s): 195
