C is the correct answer, which is the larger the number of students Terrance surveys, better his estimate of the mean will be
Answer:
$23.11
Step-by-step explanation:
We can use a proportion to find the meal tax
7 : 100 = x : 21.60
x = (21.60 * 7)/100 = $1,512
Final cost = 21.60 + 1,512 = $23.11
B=160+ 5c
b= 304- 3c
160+5c=304-3c
+3c +3c
160+8c=304
-160 -160
8c= 144
c=18
B will be the correct answer
