The correct choice is A. I hope this assists you.
The correct calculation yields 6.75. Dividing the number by 8 results in 6.75.
8.25 inches after multiplying the 3/4 by 2, and adding that to the previous 3/4, gives you the final height of the plant.
Answer: the boy won 10 games
Step-by-step explanation:
Let's denote B for the games won by the boy, and F for the games the father won.
We know that there are a total of 26 games:
B + F = 26.
For each game the boy wins, he gains 8 cents, while for each game lost to his father, he loses 5 cents. Since at the conclusion of the 26 games his total earnings net to zero, we have:
B*8 + F*(-5) = 0.
Now we form a system of equations:
B + F = 26
8*B - 5*F = 0.
Our first move is to isolate one variable. We'll start by expressing F in terms of B using the first equation:
B + F = 26
F = 26 - B.
Now substituting this into the second equation gives us:
8*B - 5*F = 0
8*B - 5*(26 - B) = 0
8*B + 5*B - 5*26 = 0
13*B = 5*26
B = 5*26/13 = 5*2 = 10
Thus, the boy emerged victorious in 10 games (the father won the remaining 16 games).
