Renea wants to buy a new house for $240,000.the bank requires the tenth of the cost of the house as a down payment. renae's mother volunteered to pay a third of the down payment as gift to her daughter.

240,000 = how much the house costs
24,000 = is the amount for a down payment. (1/10 the original cost)
8,000 = the amount of the down payment her mother is paying for (1/3 of the down payment)

Thus she needs to pay 16,000$ to pay off the down payment

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
