Answer:
Electricity bill is 175
Step-by-step explanation:
Given
[tex]Rent = 1800[/tex]
[tex]Gas = 150[/tex]
[tex]Each\ Roommate = 425[/tex] monthly
[tex]Number\ of\ Roommate = 5[/tex]
Required
Determine the electricity bill
If each roommate pays 425, then 5 roommates pay 5 * 425
[tex]Total = 5 * 425[/tex]
[tex]Total = 2125[/tex]
This implies that: the monthly cost of room, gas and electricity add up to 2125.
In other words,
[tex]Gas + Rent + Electricity = 2125[/tex]
[tex]150 + 1800+ Electricity = 2125[/tex]
[tex]1950+ Electricity = 2125[/tex]
[tex]Electricity = 2125 - 1950[/tex]
[tex]Electricity = 175[/tex]
Hence, the electricity bill is 175
