Lets simplify this step by step, shall we.

: Equation

.
Where :

.
This leads to

.
Now we have to

.
</span>Where:
A 30% The answer is A because if you multiply 50 by .60 % your answer will be 30.
Answer:
$27
Step-by-step explanation:
According to your question. The complete cost was $135 for a fifteen feet long beam. If you are looking for the price per yard, a yard has three feet, therefore in fifteen feet, there are five yards.
15 divided into 3 equals 5
$135 divided into five equals $27
I hope this helps.
The numerical expression that represents the total number is parentheses 15 divided by 3 plus parentheses 30 divided by 5
7,200 = (24)(20)h
15=h (just divide)
To check, 20*24*15 = 7,200 cubic centimeters so 15 cm is right
