For every 3 chocolate bars that Shannon has, Irene has 5 more chocolate bars than her. They have 55 chocolate bars altogether. How many chocolate bars does Irene have?
Number of chocolate bars that Irene has in 1 set
= 3 + 5
= 8
Total number of chocolate bars in 1 set
= 8 + 3
= 11
Number of sets
= 55 ÷ 11
= 5
Number of chocolate bars that Irene has
= 5 x 8
= 40
Answer(s): 40
