He was 21 in 1980,
There are twelve years in between them all so you subtract 36 from 78 and since he was double as old as Nancy, and Manual was the same age as her, you would divide 42 into two parts, Ric and the 10.5 year olds, and Ric would be 21 in 1980.

Answer:

$4

Step-by-step explanation:

Quick tip about 20% tips.

Move the decimal over 1 place to the left and multiply by 2.

For this equation it would look like this:

18.37 ---> 1.837

(1.837)(2) = 3.674

So, if we rounded to the nearest dollar like the question is asking then we round to $4.

Another way to do this is to multiply 18.37 by .20:

(18.37)(.20) = 3.674

Either way it is $4.

If candidate receive majority of 1st place votes they should be the winner: Borda Count can violate
irinina [24]

Answer:

B should have been the winner. Since B received the majority of the votes, he should be the winner, not A, and it doesnt matter how close was the election or how cmany votes A got in reality. If B had more votes for 1st place, then it should be the winner, not A. I am assuming that there were electoral fraud and someone intentionally didnt count valid votes from B.
