Answer:
the answer is D 6,280
Step-by-step explanation:
Since it says difference you subtract, 86 is below sea level so it'd be -86
the equation would be 6,194 - (-86)
6,194+ 86 = 6,280
Well if she added three blue and four red originally, and is now using 16 red then we would divide 16 by the original four. Which means to get the number of blue we are gonna end up multiplying by four. So three times four is twelve. Which means she would use 12 blue and 16 red to get the same color she got with 3 blue and 4 red earlier. The equation, lets use x for blue and y for red, would be 4(3x + 4y) = desired color
