In a college of 400 students, 45% are girls. Of the boys, 30% are football players. How many boys are football players? A.60
B.66
C.72
D.75

B. 66

Step-by-step explanation:

45% of 400

.45 x 400 = 180     (number of girls)

400 - 180 = 220     (number of boys)

30% of 220

.30 x 220 = 66

B

Step-by-step explanation:

100%-45%=55%

55% of 400=220

There are 220 boys in the college.

30% of 220=66

B. 66 boys are football players

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
