At a company meeting, there were 996 people in attendance. 25% of them were managers. How many managers were in the meeting?
nalin [4]

They are asking for managers so 996 of them are there, 25% are managers

Change the percent to a decimal (divide the percent number by 100)

You get 0.25

So multiply 996 by 0.25

You get 249

So there are <u>249 managers at the meeting</u>

2.) debt ratio is calculated by____.
Nonamiya [84]
2)Since the score is 750, then the annual rate is 9.25% (see the table)
Then monthly rate:9.25/12=0.77%.
Then compute 0.77% from <span> $2,375.00 like this:
</span>0.0077\times2375=\$18.30
Answer: interest to pay: $18.30.

3)Compute monthly rate for first account:
9.75/12=0.81%
Compute 0.81% of  $<span>1,675.00 like this:</span>0.0081\times1675=13.5
Second account:
compute monthly rate: 12.5/12=1.04%.
Then compute 0.0104\times1,675.00=17.4
Conclusion:
Monthly interest is $13.5+$17.4=$30.9
