Sid brought $200 to the amusement park . the cost of admission is $16.25 , and the cost of a lunch is $6.50 . After Sid purchased an admission ticket and a lunch for each person in his group , he had $18.25 left. How many people are in Sid´ s group ?
A. 4
B.5
C.6
D.7

Answer 1

Let x represent the # of people in sid’s group: 200 - (16.25x + 6.50x) = 18.25
200 - 22.75x = 18.25
-22.75x = -181.75
x = about 8

if Sid is not included in the group, i think the answer is D. 7, but im not sure
