Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out \frac{2}{3} of the chocolate bars and \frac{3}{5} of the toffee bars. How many packages of chocolate bars did Rasheed buy?

Rasheed bought 9 packages of chocolate bars

Step-by-step explanation:

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each.

Let 'cb' represent the number of chocolate bars that Rasheed bought

Let 'tb' represent the number of toffee bars that Rasheed bought

If Rasheed bought 1 fewer package of chocolate bars than toffee bars; we have the following suitable expression

cb = tb - 1

Also; he handed out of the cb and of tb; we have:

If we make tb the subject of the formula since we are only looking for the number of chocolate bars Rasheed bought; we have:

From the previous expression cb = tb - 1

1 = tb - cb

Replacing in the above equation; we have:

cb = 9

Hence,Rasheed bought 9 packages of chocolate bars
