Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
This is a ratio problem. You only need solve the ratio of the sand.
<u> 48 </u> <u /> = <u> n </u> <u />
1 156
(48)(156) = 1(n) (cross multiplying)<span>
</span>
7,488 pounds
To check: The pool deck is 156 times larger than the original amount of concrete so the amount of sand needs to be 156 times more.
