Which of the following ribbon has the greatest cost per inch?
a) 30 inches for $1.80
b) 24 inches for $1.92
c) 42 inches for 2.94
d)36 inches for $3.24
**guyss i need its my math homework and is 4 ! **

It would be D because 3.24 divided by 36 is .09 which is the highest of all

For Part A, since we know that 850 teenagers were surveyed and 32% of them like hard rock, we can solve using the following method:
1) First, we can multiply 850 by 32% or 0.32. That gives us 272.
2) Now, we know that out of the 850 kids surveyed, only 272 like hard rock.

For Part B, since we know that 75% of the kids surveyed, which can also be known as 150 teenagers, we can solve using the following method:
1) First, we can divide 150 by 3, since we know that 75 is 3/4 of 100. That gives us 50.
2) Now we can add 50 to 150, which gives us a total of 200 students that were surveyed.

For Part C, an example in which a percentage greater than 100% could have to do with vitamin and nutrition intake, or change in world population. An example could be: the world population increased by 500% from 1804 to 1999.

I hope this helps you!
