I need help in solving this word problem using linear system equation...I.m not sure how to start,,,
A hotel rents a double occupanch room for $20 more than a single occupancy room. One night, the hotel took in $3115 after renting 15 double occupancy rooms and 26 single occupancy room. I need to write and solve a linear system equatio to find the cost of renting a double occupancy room and the cost of renting a single occupancy room...I don't know where to start...please help I'm confused.
...

let rental of single room be x dollars,
then rent for double room is x+20
15x + 26(x+20) = 3115
I leave it up to you to solve that simple equation.
