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?
O 0.15(40) + 0.6x = 0.25(40+ x)
O 0.15(40) + 0.6(x - 40) = 0.25(x)
O 0.15(40) + 0.6x = 0,25(40 - x)
O 0.15(40) + 0.6(x +40) = 0.25(x)
