Her bank can hold 360 pennies.

Explanation:

Her bank was half full. Then, when she adds 120. It is 2/3. This would mean the 120 is 2/6 the amount the bank can hold. You would multiply that by 3 to get the total amount. That amount being 360.

Do you have any questions? Did I calculate something wrong?

Please tell me! I am happy to help people!

united services and supplies reports net income of $100000 and cost of goods of $353000. If US&amp;S's gross profit rate was 30%
deff fn [24]

Answer:

Net sales is $ 504285.71

Step-by-step explanation:

We have the following:

Let net sales be x.

Net sales - Cost of goods sold = Gross profit

We replace and we are left with:

x - $ 353000 = x * 30%

x - $ 353000 = 0.30 * x

x - 0.30 * x = $ 353000

0.7 * x = $ 353000

x = $ 353000 / 0.7

x = $ 504285.71

Therefore, net sales is $ 504285.71
