I am pretty sure this has to be true. I go back to basic sequence and series, if $0 \leq (a_k) \leq (b_k)$, I know that if $\Sigma_{k=1}^{\infty}(b_k)$ converges, then $\Sigma_{k=1}^{\infty}(a_k)$ converges.
Then I just need to apply the Weierstrass M-test to the series of functions, right?
Thanks!
