We don't know what the values of the resistors are.
They must have been given in the previous problem.

But the total resistance of a series circuit is just the sum of
all the resistors in it. So find out what the three resistances are,
and just addum mup !

R_\Sigma = R_1 + R_2 + R_3 = 34 \ \Omega.
