The two with the algebra are set up wrong. If set up correctly, the water is 1 dollar and the chocolate bar is 10. It does not say two bottles of water were bought. The one brick is equal to 1 brick and a half a brick doesn't make any sense unless they were different sizes and even then it would be x = 1 + 0.5. not brick = brick plus half a brick plus half a brick. The bottle of water one should be set up as x + 10 = 11 and the brick should be 1 + 0.5 = 1.5. SMH. If you're going to post something like that, make sure they are correct.
