Community Colleges w/4 credit hour summer courses

My daughter attends a college with a 4 credit hour structure. She’d like to take a summer class (Intro to Finance) to lighten her load. She can take them at her university but it would be nice to save some $. Does anyone know of community colleges that grant 4 credit hours? Thank you.

She needs to find out what the policy at her college is about transferring credits. Can they recommend a specific place for her to get that class during the summer? If it is a prerequisite for a class she wants to take in the fall, she needs to be certain that the correct topics will be covered. Whether the class is 3 or 4 might not matter that much. But the content probably will.
