Nancy bought 360 tropical fish for a muesem display. she bought 8 times as many goldfish as angelfish. how many of each type of fish did she buy?
which system of equation models the problem if x represents the number of angelfish nancy bought and y represents the number of goldfish 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

41*67/2=1373.5
