at deluxe paint store , fuchsia paint is made by mixing 4 parts of red paint with 2 parts of blue paint . mauve paint is made by mixing 3 parts of red paint with 6 parts blue paint . how many liters of blue paint must be added to 24 liters of fuchsia to change it to mauve paint ?
"in 24 liters , red = 4 / 6 * 24 = 16 and blue = 8 so , 16 / ( 8 + x ) = 3 / 6 or , x = 24 ( answer e )"
subtract(multiply(divide(multiply(24, divide(4, add(4, 2))), divide(3, add(4, 2))), divide(6, add(4, 2))), subtract(24, multiply(24, divide(4, add(4, 2)))))
