You have $6 and earn $0.50 for each cup of orange juice you sell. write an equation in two variables that represents the total amount a (in dollars) you have after selling j cups of orange juice. a = ? is it a = .50j + 6 and if it is explain .

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
