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?
Thoughts? Step-by-step reasoning:
Purity will pay a third of Rose's share, which translates to 1800 / 3 = 600 dollars. Sheila has offered to pay 5 * 600 = 3000 dollars. Combining everyone's share of the rent will give a total of 600 + 3000 + 1800 = 5400 dollars.
Thus, the answer is 5400.
