Word problem solve using a system of equations

At a concession stand, 100 bottles of water and pretzels were sold for a total of \$250. If one bottle of water costs \$1.50 and one bottle of pretzel costs \$3.50, how many of each were sold?

What have you done so far? It is hard to help you find what is wrong with your work if you do not show it.

It's rather obviously 50 bottles of each.

To use a system of equations, I suggest w + p = 100, with a second equation that incorporates the prices.
