Which system of equations models the problem if x represents the number of parrotfish jenna bought and y represents the number of triggerfish she bought? jenna bought 280 tropical fish for a museum display. she bought 4 times as many triggerfish as parrotfish. how many of each type of fish did she buy? {x+4y=280y=4x {x−y=280y=4x {x+y=280y=4x {x+y=4y=280x
