Total number of chocolate bars
= 10 u + 4 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 Vanessa gave to Joelle and Pamela
= 10 u - 5 u
= 5 u
5 u = 40
1 u = 40 ÷ 5 = 8
Total number of chocolate bars
= 15 u
= 15 x 8
= 120
Answer(s): 120
