3,230
Step-by-step explanation:
We can solve
this problem by using the formula:
1 +
fractional increase = (original employees + new employees) / original employees
Lets say,
x = original
employees
Therefore
substituting the known values:
1 + 0.05 = (x
+ 30) / x
1.05 x = x +
30
0.05 x = 30
x = 600
Therefore
the number of employees working now is:
<span>x + 30</span>
<span>= 630
employees</span>
Solution: Let "m" be the number of marbles Santana has.
First he wants to give one-tenth of his marbles to his brother. That is:
He also wants to give 8 more marbles to his brother.
Therefore,
Santana wants to give marbles to his brother
8 + 8 + 8 + 7 + 7 + 8 + 3 = 49
49 / 7 = 7
The mean is 7
