Lets use the equation that the question has given us:
y=1.377x+137.763
we know that y is the cost of two bedroom apt and x is the cost of one bedroom apt so lets use the cost of one bedroom apt that they gave us 724 Therefore, x=724 Lets put that into our eqn y=1.377(724)+137.763 y=1134.711 rounded up y=1135 So the answer is 1135
