C.6 + 30 = 62
D.ax – by = k

Answers

ANSWER

$ax-by=k$ is an example of literal equation.

EXPLANATION

A literal equation is an equation in which letters or variables are used to represent real values.

A literal equation consists of at least two letters or variables.

The first option consists of two variables but it is not an equation. It is just an expression.

The second option is not a literal equation because it consists of only one variable. This is just a linear equation in one variable. But a literal equation should have at least two variables or letters.

As for the third option, it does not even contain a variable or letter.

Choice D. represents a literal equation

Which of the following employees has the greatest total employee compensation?a.
Employee A: total job benefits $49,200 and total job expenses $300
b.
Employee B: total job benefits $49,500 and total job expenses $500
c.
Employee C: total job benefits $ 49,800 and total job expenses $700
d.
Employee D: total job benefits $50,100 and total job expenses $900

Answers

We have to choose the correct answer which of the employees has the greatest total employee compensation. We just have to subtract the job expenses from total job benefits for everyone of them. A: $49,200 - $300 = $38,900. B : $49,500 - $500 = $49,000. C : $49,800 - $700 = $41,100. D : $50,100 - $900 = $49,200. The largest sum is $49,200 ( employee D ) . Answer: The greatest total employee compensation has Employee D.

D: Employee D: Total employee benefits $3,000 Total job benefits $52,300
