<human>:  Sheila, Purity, and Rose want to rent a house. Sheila has offered to pay five times Purity’s share of the rent. Rose can only afford thrice what Purity pays. If Rose’s share is $1,800, what is the total house rent?
<bot>: How much will Purity pay? ** Purity will pay a third of Rose's share, which translates to 1800/3 = <<1800/3=600>>600 dollars.
How much will Sheila pay? ** Sheila has offered to pay 5 * 600 = <<5*600=3000>>3000 dollars
What is the total house rent? ** Combining everyone’s share of the rent will give a total of 600 + 3000 + 1800 = <<600+3000+1800=5400>>5400 dollars
#### 5400
