Ответ:
900 and $250
Step-by-step explanation
Given data
Total cost of utilities per month =$1150
Let the cost of rent be x
And the cost of electricity be y
x+y=11501
It costs $650 more for rent per month than for electricity
x=x+6502
From equation 1
x+x+650=1150
2x=1150-650
2X=$500
x=500/2
x=$250
Hence the cost of electricity is $250
And the cost of rent is $650+250
=$900
