Question

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 of 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?

a) x - y = 360
y = 8x

b) x + y = 360
y = 8x

c) x + y = 8
y = 360x

d) x + 8y = 360
y = 8x

Answer 1

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.

Answer 2

I think the answer is C.
