Ipatiy [6.2K]

m = 16
8 6


Cross multiply:
m * 6 = 8 * 16

Simplifying
m * 6 = 8 * 16

Reorder the terms for easier multiplication:
6m = 8 * 16

Multiply 8 * 16
6m = 128

Solving
6m = 128

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Divide each side by '6'.
m = 21.33333333

Simplifying
m = 21.33333333

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.
