Roxanne has a total of 50 bracelets and necklaces. Three times the number of bracelets minus the number of necklaces is 10. How many of each does Roxanne have?
Answer provided by our tutors
let
b = the number of bracelets
n = the number of necklaces
Roxanne has a total of 50 bracelets and necklaces
b + n = 50
3 times the number of bracelets minus the number of necklaces is 10
3b - n = 10
by solving the system of equations
b + n = 50
3b - n = 10
we find
b = 15 bracelets
n = 35 necklaces
