Yves bought 420 tropical fish for a museum display. He bought 6 times as many parrotfish as angelfish. How many of each type of fish did he buy?
Which is a system of equations to model the problem if x represents the number of angelfish Yves bought and y represents the number of parrotfish he bought?
A.
x + y = 6
y = 420x
B.
x + 6y = 420
y = 6x
C.
x – y = 420
y = 6x
D.
x + y = 420
y = 6x
