Question

Can someone Write and solve a linear system to find the cost of renting a double-occupancy room and the cost of renting a single-occupancy room. (See Q in comments)

Answer 1

A hotel rents a double-occupancy room for $30 more than a single-occupancy room. One night, the hotel took in $3115 after renting 15 double-occupancy rooms and 26 single-occupancy rooms.

Answer 2

single: $65
double: $90

Answer 3

$95 my bad

Answer 4

Can you write a linear equation for it too please ?

Answer 5

I'm not really good at that but...here's the work
let single room as 'S' and double room as 'S+30'.
So, 15(S+30) + 26(S) = 3115
41(S) + 15(30) = 3115
41(S) + 450 = 3115
41(S) = 3115 - 450 = 2665
S = 2665/41 = 65.

So single room cost = 65.
And double room cost = 65 + 30 = 90.
