Jonathan has 30 chocolates. he gives some chocolates to his friend david. he then gives sarah half the number of chocolates that he gave david and gives lily two-thirds of what he gave david. after giving away the chocolates, jonathan has 4 chocolates left. if the number of chocolates jonathan gives david is x, which equation represents the situation? how many solutions does this equation have? a. x + 1/2x + 2/3x = 30 - 4, which has no solution. b. x + 1/2x + 2/3x = 30, which has infinitely many solutions. c. x + 1/3x + 2/3x - 4 = 30, which has one solution. d. x + 1/2x + 2/3x + 4 = 30, which has one solution. e. 1/2x + 2/3x = x - 4, which has no solution.
