Question

PLEASE HELP

bill is twice as old as joyce and sam is 5 years older than bill . the sum of their ages is 100. joyce is n years old, how old is sam?

Answer 1

Since Joyce is n years old, Bill is 2n years old and Sam is 2n + 5 years old. Altogether, they are 5n + 5 years old, which is 100.

5n + 5 = 100

n = 19

Thus, Sam is 43 years old.
