Answer:

$22.40

Step-by-step explanation:

To find the amount of sales tax you have to multiply the price by the decimal form of the percent of sales tax.

In this situation, you would multiply 320 by .07.

(320)(.07) = 22.40

Therefore, the amount of sales tax is $22.40.

I hope this helps!!

Step-by-step explanation:

Given:

The ratio of almond, wheat and corn = 3:5:7.

To Find:

Amount of this mixture contains 9 kg of almond =?

Solution:

The total of the fraction = 3+5+7 = 15

Let the total amount of the mixture be X, then

Then

$\frac{ \text{ratio of the almond in the mixture}}{\text{total ratio}} \times X = 9$

$\frac{3}{15} \times X = 9$

$X = 9 \times \frac{15}{3}$

$X = 9 \times 5$

X = 45
