Minchanka [31]

Answer:

  2.34 grams

Step-by-step explanation:

The first 3 digits of the number are 2, 3, 3. The next digit is 5, which is more than 4, so 1 is added to the digit to its left and all digits to the right of the first three are dropped.

2.33 becomes 2.34 because of the 5 in the thousandths place.

Your rounded measurement is 2.34 grams.

You have been averaging 55 sales per day. Per our new policy, everyone needs to increase his or her sales per day by 10% in the
Mariulka [41]
To find your new number of sales per month, you will need to find the number of sales you have per month (based on 30 days per month).  

55 x 20 = 1650 sales.

Than, you will need to calculate what 10% of this is and add it to your original sales number.

0.1 (10%) x 1650 = 165

1650 + 165 = 1815

You will need approximately 1815 sales based on the 30 day month.
