aniked [119]

$\dfrac{x^{-9}y^3}{x^{-7}y^8}=x^{-9-(-7)}y^{3-8}=x^{-2}y^{-5}=\dfrac{1}{x^2y^5}\\\\Used:\\\\\dfrac{a^n}{a^m}=a^{n-m}\\\\a^{-n}=\dfrac{1}{a^n}$

melisa1 [442]

Answer:

$Earnings = 308.75$ ---- (a)

$Earnings = 300 + 0.05x$ -- (b)

Step-by-step explanation:

Given

$Base\ Salary = 300$

$Commission = 5\%$

Solving (a): Sales of $2175 in a week.

His total earnings is calculated as thus:

$Earnings = Base\ Salary + Commission * Sales$

$Earnings = 300 + 5\% * 2175$

$Earnings = 300 + 108.75$

$Earnings = 308.75$

Solving (b): Sales of $x in a week.

His total earnings is calculated as thus:

$Earnings = Base\ Salary + Commission * Sales$

$Earnings = 300 + 5\% * x$

Convert percent to decimal

$Earnings = 300 + 0.05 * x$

$Earnings = 300 + 0.05x$
