Fifteen percent of the pigment in paint color A is black. Sixty percent of the pigment in paint color B is black. An unknown amount of paint color B is mixed with 40 ml of paint color A, resulting in a paint that contains 25% black pigment.
Which equation can be used to solve for x, the total amount of paint in the mixture of the two colors?
0.15(40) + 0.6x = 0.25(40 + x)
0.15(40) + 0.6(x β 40) = 0.25(x)
0.15(40) + 0.6x = 0.25(40 β x)
0.15(40) + 0.6(x + 40) = 0.25(x)
