4) A coach is buying snacks for 22 players at a soccer match. She pays a total of \( \$ 77 \) to buy each player a bottle of water and an energy bar. The price of one energy bar is \( \$ 2 \). (4)) Which quantity is unknown? (4)) the price of a bottle of water Let \( w \) equal the price of a bottle of water. Write an equation that reprents the situation.

In this scenario, the coach is buying snacks for 22 players, which means she's purchasing 22 bottles of water and 22 energy bars. Since each energy bar costs $2, the total cost for the energy bars would be \( 22 \times 2 = 44 \) dollars. To find the total cost of the snacks, we can represent the price of the water bottles with \( w \). Therefore, the equation representing the situation is \( 22w + 44 = 77 \). Now, solving this equation will yield the unknown price of each bottle of water, which can help the coach stick to her budget and ensure all players are well-fed and hydrated during the match!
