Answer:
$8000
Step-by-step explanation:
The method for calculating simple interest (I) is
I = 
where P is the principal, R is interest rate, T is time in years
here I = 1120, R = 3.5, T = 4 and P is to be found, thus
1120 = 
( multiply both sides by 100 )
3.5 × 4 × P = 112000
14P = 112000 ( divide both sides by 14 )
P = 
= $8000
Number employees N = 600
Then
Probability of Single + College degree = ?
Probability of single S = 100/600 = 1/6
Probability of College graduate G = 400/600 = 2/3
So then probability of both S and G is
Prob Single or Graduate = 1/6 + 2/3 = 1/6 + 4/6 = 5/6
. = 0.833
Then answer is
Probability of Single or Graduate = 5/6= 0.8333
Is also 83.33%
You multiply 2 by 0.085 and you get the answer
$0.17
Then add $0.17 and $2 and you get $2.17
Lets look at the hours they are open from. 9 am - 4:30 pm which is 7 and a half hours a day. Now we multiply 7 1/2 by the number of days they are open, which will be 7 1/2 * 255 = 1,912.5. This means that the library is open 1,912 1/2 hours a year.
I hope I've helped! :)
