Final answer:
We cannot determine Jenna's royalties without knowing the specific royalty rates for radio plays and downloads. If this information is provided, a calculation could be performed to find the correct answer.
Step-by-step explanation:
To determine how much Jenna received in royalties during January for her song played on the radio and downloaded, we need to know the royalty rates for radio plays and downloads. However, since the question does not provide the specific rates, we cannot calculate the exact amount of royalties Jenna would receive.
Without the royalty rates, any answer given would be a guess. Presumably, the question intended to include additional information regarding the royalty rates per play and per download, which would be necessary to perform the calculation. If the student can provide these rates, we can proceed to calculate Jenna's royalties based on the given frequencies of radio plays and downloads.
