To find out how much Olivia got, we need to find the ratio between Olivia and Sylvia's amounts in the same way.
The ratio between Olivia and Sylvia is 2:3.
Let's set up a proportion to find out how much Olivia got.
2/3 = x/21
To solve for x, we can cross multiply.
2 * 21 = 3 * x
42 = 3x
To isolate x, we divide both sides by 3.
42/3 = x
14 = x
Therefore, Olivia got $14.
