Kurt is buying a watch that had an original price of $195 but is advertised as 35% off. Sales tax of 8.75 % is applied to the di

Schach [20]

Answer:

$137.84

Step-by-step explanation:

We have been given that Kurt is buying a watch that had an original price of $195 but is advertised as 35% off. Sales tax of 8.75 % is applied to the discount price. We are asked to find the amount paid by Kurt for the watch.

First of all, we will find discounted price of watch by calculating 65% of original price as 100% minus 35% is 65%.

$\text{Discounted price of watch}=\$195\times \frac{65}{100}$

$\text{Discounted price of watch}=\$195\times0.65$

$\text{Discounted price of watch}=\$126.75$

Now we will add 8.75% of $126.75 to $126.75 to find price of watch after sales tax.

$\text{Price of watch after sales tax}=\$126.75+\$126.75\times \frac{8.75}{100}$

$\text{Price of watch after sales tax}=\$126.75+\$126.75\times 0.0875$

$\text{Price of watch after sales tax}=\$126.75+\$11.090625$

$\text{Price of watch after sales tax}=\$137.840625$

$\text{Price of watch after sales tax}\approx \$137.84$

Therefore, Kurt will pay $137.84 for the watch.

Rewrite the following expression.

faust18 [17]

We have been given the expression

$x^{\frac{9}{7}}$

We have the exponent rule

$x^{\frac{a}{b}}= x^{a^{(\frac{1}{b})}}$

Using this rule, we have

$x^{\frac{9}{7}}= x^{9^{(\frac{1}{7})}}$

Now, using the fact that $x^{\frac{1}{n}}=\sqrt[n]{x}$ , we get

$x^{\frac{9}{7}}= \sqrt[7]{x^9}\\
\\
x^{\frac{9}{7}}=\sqrt[7]{x^7\times x^2}\\
\\
x^{\frac{9}{7}}=x\sqrt[7]{x^2}$

D is the correct option.
