Solve 1.5n + 4 = 4n + 4 for n, which represents the integer location on a number line. Which option best checks and interprets the result?
A
n = 0, and 1.5(0) + 4 and 4(0) + 4 both equal 4, but it is not reasonable. It is not reasonable because the value should be positive.
B
n = 1, but 1.5(1) + 4 = 5.5 and 4(1) + 4 = 8, so this value does not solve the equation.
C
n = 0, and 1.5(0) + 4 and 4(0) + 4 both equal 4, so the solution is reasonable. The value stays a whole number, and negative values are allowed if needed.
D
n = -1, but 1.5(-1) + 4 = 2.5 and 4(-1) + 4 = 0, so this value does not solve the equation.
