For number 15, all you need to do is multiply 36 by 25 which gets you 900 square yards. For #16, you would also want to use multiplication, 3 * 39 ($117) , 4 * 15 ($60) and 27 * 2 ($54). Now add them together, 54 + 117 = 171 + 60 = $231. And finally break down the number 309 million, 058 thousand, 304 hundred. Four, eight and, nine need to be in the ones place. So you have 309,058,304, C.
