The projected number of employed writers and authors in 2016 is 153,000. 12.4% of those will have some college experience but no degree, and 84.1% will have a bachelor’s degree or higher. if this holds true, how many more writers and authors with bachelor’s degree will there be than those with only some college experience and no degree?

1. Count 12.4% of 153,000:

153,000 - 100%,

x - 12.4%

Mathematically, you can write proportion:

2. Count 84.1% of 153,000:

153,000 - 100%,

y - 84.1%

Mathematically, you can write proportion:

3. There will be 128,673 writers and authors with bachelor’s degree and 18,972 writers and authors with some college experience and no degree. Then the difference is

128,673-18,972=109,701.

writers and authors with bachelor’s degree will be there 109,701 more than those with only some college experience and no degree

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
