13.60 because you add the coupon discount back on and subtract tax cost and divide by 2
Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
801 rounded to the nearest ten would be 811
It is basically 8 thousand plus one thousand two hundred so your answer would be 9200
The answer is D you put 10/5 then simplify
