Which two expressions can be used to answer this question?
45% of the 647 students at Royal Oak High attended the football game. How many students did not attend?
A) 647 - 0.45(647); 0.55(647)
B) 647 - 0.45(647); 0.45(647)
C) 647 + 0.45(647); 0.45(647)
D) 647 - 0.55(647); 0.55(647)
i think its c
45% attended
100% is everybody, so 100-45 = 55% did not attend
so, you want
0.55 * 647
the answer is A guys
d
To find the number of students who did not attend the football game, we need to calculate 55% of the total number of students, since 45% attended.
The correct expressions would be:
A) 647 - 0.45(647); 0.55(647)
and
D) 647 - 0.55(647); 0.55(647)
In both cases, we subtract 0.45 times the total number of students to find the number of students who attended, and subtract this value from the total number of students to find the number of students who did not attend.
