A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the number of adults. The number of female students was half the number of male students. If the total number of people who went on the trip is 82, find the numbers of male students and female students.

Best ResponseYou've already chosen the best response.3Lets start by labeling anyways let \(a\) = number of adults \(m\) = number of male students \(f\) = number of female students

Best ResponseYou've already chosen the best response.3`The number of male students was 1 more than 7 times the number of adults.` translates to \[m = 7a+1\tag{1}\]

Best ResponseYou've already chosen the best response.3`The number of female students was half the number of male students` translates to \[f=\frac{m}{2}\tag{2}\]

Best ResponseYou've already chosen the best response.3basically we have 3 equations and we need to solve 3 unknowns : \(a, m, f\)

Best ResponseYou've already chosen the best response.3\[m = 7a+1\tag{1}\] \[f=\frac{m}{2}\tag{2}\] \[a+m+f = 82\tag{3}\] rearranging second equation gives, \(m=2f\) plug this in the remaining equations

Best ResponseYou've already chosen the best response.3\[2f = 7a+1\tag{4}\] \[a+2f+f=82\tag{5}\] can you solve this new two equation system with two unknowns ?

Best ResponseYou've already chosen the best response.3You could do that if you want to use substitution

Best ResponseYou've already chosen the best response.3\[2f=7a+1\] dividing 2 both sides gives \[f=\dfrac{7a+1}{2}\] you want to plug this in the other equation and solve \(a\) is it ?
