in a survey of 50 students from grant middle school 11 had eaten mexican food within the past seven days if there are 600 students at school how many would you expect to have eaten mexican food within the last seven days

a)11
B)50
C)132
D)550

please tell how you got your answer THANK YOU!!!
 
the sample 50 is 1/12 of the school population (600)
so I would expect 11(12) = 132 to have eaten Mexican food within the week.
