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
