Answer:
12 blue chips 8 red chips.
Explanation:
Let's call the number of blue chips "b" and the number of red chips "r". We know that 2 blue chips for every 3 red chips, so we can set up the following equation:
2b = 3r
And we know that there are 20 total chips, so:
b + r = 20
Now we can use substitution to find the value of b. We'll substitute the expression for r from the first equation:
2b = 3(20 - b)
Expanding the right side:
2b = 60 - 3b
Combining like terms:
5b = 60
And finally, solving for b:
b = 12
So there are 12 blue chips and 20 - 12 = 8 red chips.
