Each of the three oldest children sleeps in a twin bed. they all need bed sheets.a brand of sheets is on sale for "but one get one at 50% off".if each sheet costs $18.00, how much will two sheets cost? how much will six sheets cost?

50% of 18 = 9

 so buy 1 for 18 and 1 for 9 = 18+9 = 27 for 2 sheets

6/2=3

27 x 3 = 81 for 6 sheets

Given:
Price of the house = 115,732.80
down payment = 10% of the price

115,732.80 * 10% = 11,573.28

Gross monthly salary = 2,624
expenses:
monthly = 1,150.12
sss = 2,624/2 = 1,312 * 6.2% = 81.34
medicare = 1,312 * 1.45% = 19.02
State and Federal taxes: 53 + 101.35 = 154.35
Total Monthly expenses = 1,404.83

2,624 - 1,404.83 = 1,219.17

11,573.28 / 1,219.17 = 9.5 month or 10 months.
