Tanya has 7 half-dollars and 5 quarters.
Given that Tanya has 12 coins in half-dollars and quarters, and their total value is $4.75, to determine how many coins are there of each type, the following calculation has to be made:
- 12 x 0.5 + 0 x 0.25 = 6
- 10 x 0.5 + 2 x 0.25 = 5.5
- 8 x 0.5 + 4 x 0.25 = 5
- 6 x 0.5 + 6 x 0.25 = 4.5
- 7 x 0.5 + 5 x 0.25 = 4.75
Therefore, Tanya has 7 half-dollars and 5 quarters.
