For every 5 chocolate bars that Usha has, Rachel has 9 more chocolate bars than her. They have 57 chocolate bars altogether. How many chocolate bars does Rachel have?
Number of chocolate bars that Rachel has in 1 set
= 5 + 9
= 14
Total number of chocolate bars in 1 set
= 14 + 5
= 19
Number of sets
= 57 ÷ 19
= 3
Number of chocolate bars that Rachel has
= 3 x 14
= 42
Answer(s): 42
