A class of 80 girls and 60 boys sponsored a car wash. If 40 percent of the girls and 30 percent of
the boys got their cars washed, approximately
what percent of the class got their cars washed?
O A. 91%
OB. 64%
OC. 50%
OD. 36%

36%

Step-by-step explanation:

class total: 140 students

40% of 80= 32

30% of 60=18

18+32= 50

50 divided by 140= .36 or 36 percent

answer: f = 32.2m

step-by-step explanation: that is the answer

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
