Nancy bought 360 tropical fish for a museum display. She bought 8 times as many gold fish as angel fish. How many of each type o
f fish did she buy? Which is a system of equation to model the problem if x represents the number of angel fish Nancy bought and y represents the number of gold fish she bought?
The answer is b. if you think about it, the details say that she bought 360 fish, 8 times more than goldfish than angel fish. if the gold fish were x, and the angle fish were y, it would be x+y=360 with y=8x. it is addition because the TOTAL is a combination of angel fish and gold fish. you aren't subtracting anything.
