Question 1208006
<br>
Here is a solution using one of many possible ways of setting the problem up.<br>
Given that 2/5 of the rubber bands were red...<br>
Let 2x = # of red
Then 5x = total number
and 5x-2x = 3x = # of blue and green<br>
40 = # of green (given)
2x+24 = number of blue (24 more than the number of red)<br>
The equation to solve now uses two expressions we have for the number of blue and green:<br>
{{{40+(2x+24)=3x}}}
{{{2x+64=3x}}}
{{{x=64}}}<br>
The total number of rubber bands is 5x = 5(64) = 320<br>
ANSWER: 320<br>
