The Highland Booster Club sells refreshments at the concession stand for local football games. Combinations include 4 hot dogs and 2 sodas for $10 and 6 hot dogs and 3 sodas for $15. Let h represent the cost of a hot dog, and let s represent the cost of a soda. Write the pair of linear equations that model this situation.
4h + 2s = 10
6h + 3s = 15
