Let's assume Maya has x quarters.

The value of x quarters is 0.25x dollars.

The value of 8 dimes is 0.10 * 8 = 0.80 dollars.

Therefore, the total value of Maya's coins is 0.25x + 0.80 dollars.

We know that the total value of the coins is no less than $3.30, so we have the inequality:

0.25x + 0.80 ≥ 3.30

0.25x ≥ 2.50

x ≥ 10

Since Maya can have a maximum of 21 coins, and we already know she has 8 dimes, the maximum number of quarters she could have is:

21 - 8 = 13 quarters

Therefore, the possible values for the number of quarters that Maya could have are 10, 11, 12, or 13 quarters.
