rusak2 [61]

Natalie’s net income for the month of October is $1,930.

<h2>Net Income </h2>

The net income of a person is the income of the person that is left with him after deducting all of his\her expenses and deductions.

\rm Net\ Income = Total\ salary - Total\ expenses - Deductions

<h2 /><h2>Given to us</h2>
  • Natalie's monthly income statement for October. Total wages are 3,000 dollars.
  • Total expenses are 1,070 dollars.

<h3 /><h3>Natalie’s net income</h3>

the total wage Natalie is already given is $3,000, and her expenses as $1,070, while there are no deductions from his salary. therefore,

\rm Natalie 's\ Net\ Income= Total\ salary - Total\ expenses - Deductions

                                 =\$3,000 - \$1,070 -\$0\\= \$1930

Answer this question ​
lutik1710 [3]

Answer:

Step-by-step explanation:

1. Eggs are sold at a price of P 105.00 per dozen.

Rate = \frac{1}{105}

2. The carpentry job can be done by 3 carpenters in 4 days.

Rate at which each carpenter works = \frac{4}{3} = 1\frac{1}{3} days

This shows that each carpenter worked for an average of 1.3333 days to complete the job.

3. Five tickets are sold at P 600.00

The price for one ticket = \frac{600}{5}

                                       = 120

One ticket is sold for P 120.00.

4. The dollar's rate is P 52.00.

This implies that;

1 dollar = P 52.00

dollar rate = \frac{1}{52}

5. The ratio of water to milk in the recipe is 1 to 4.

This implies that to 1 measure of water, 4 measures of milk is used in the recipe.

rate = \frac{1}{4}
