In order to subtract one fraction from another, we need to make the denominator the same in both fractions. The lowest common denominator is 8, because 4 is a factor of 8.
In order to make the denominators the same, multiply both the numerator and denominator of 13/4 by two. This keeps the value of the fraction the same, but will equate the denominators.
![\frac{13*2}{4*2} = \frac{26}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B13%2A2%7D%7B4%2A2%7D%20%3D%20%5Cfrac%7B26%7D%7B8%7D%20)
At this point, we can simply subtract 5/8 from 26/8.
![\frac{26}{8}- \frac{5}{8} = \frac{21}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B26%7D%7B8%7D-%20%5Cfrac%7B5%7D%7B8%7D%20%3D%20%20%5Cfrac%7B21%7D%7B8%7D%20)
21/8 cannot be simplified, so it is the answer.
92 divided by 2.8 is 32 remainder 2.4. 2.8 does into 92 about 32 times.

Step-by-step explanation:
Perhaps you want the table filled in.
Profit is the difference between revenue and cost.
Marginal anything is the change in that divided by the change in the number of units (pounds of beef). As you'd expect, the marginal profit is the difference between marginal revenue and marginal cost.
It is convenient to let a spreadsheet do these repetitive calculations.
Perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other slope is -b/a
the given line 3x-4y=24, 4y=3x-24, y=3/4x-6 has a slope of 3/4, so the slope of the perpendicular line has a slope of -4/3
y=(-4/3)x+b, b can be any number.
