Who made more choices commission this month? How much did she make? Salesperson A made 11% of $67,530. Salesperson B made 8% of

Levart [38]

Answer Step-by-step explanation:

$Salesperson~A=$ $11$ % $of~67,530=\frac{11}{100} *67530=0.11$

$=0.11*67530=7,428.3$

$Salesperson~B=$ $8$ % $of~85,740=\frac{8}{100}*85740= 0.08$

$=0.08*85740=6,859.2$

$7,428.3$ > $6,859.2$

$Thus,~Salesperson~A~made~more~commission~than~Salesperson~B.$

What is the following quotient? 2/ square root 13 + square root 11

enot [183]

Given : $\frac{2}{\sqrt{13}+\sqrt{11}}$

$\mathrm{Multiply\:by\:the\:conjugate}\:\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}$

$=\frac{2\left(\sqrt{13}-\sqrt{11}\right)}{\left(\sqrt{13}+\sqrt{11}\right)\left(\sqrt{13}-\sqrt{11}\right)}$

\left(\sqrt{13}+\sqrt{11}\right)\left(\sqrt{13}-\sqrt{11}\right)

$\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}\left(a+b\right)\left(a-b\right)=a^2-b^2$

$a=\sqrt{13},\:b=\sqrt{11}$

$=\left(\sqrt{13}\right)^2-\left(\sqrt{11}\right)^2$

$\left(\sqrt{13}\right)^2-\left(\sqrt{11}\right)^2=13-11=2$

$=\frac{2\left(\sqrt{13}-\sqrt{11}\right)}{2}$

$\mathrm{Divide\:the\:numbers:}\:\frac{2}{2}=1$

$=\sqrt{13}-\sqrt{11}$

Therefore, correct option is $D.\\\sqrt{13} - \sqrt{11}$
