if y have 50,000,000 dollars and y buy a house that costs 4,888,000 how many i have?
Balance - $50,000,000
Price of house - 4,888,000
50,000,000 - 4,888,000 = 45,112,000
New balance - $45,112,000
Though, If your question was how many houses can I buy:
50,000,000 / 4,888,000 = 10.229
So you can buy 10 houses and you have leftover.
