Given that, you may want to check the economics course listings in the catalogs of colleges under consideration. Economics major programs typically have an upper level core set of courses in intermediate microeconomics, intermediate macroeconomics, and econometrics. The math prerequisites of intermediate microeconomics and econometrics will suggest how much math emphasis the department has (some will offer more than one sequence with different levels of math prerequisites). The typical levels you may find:
No calculus (least desirable for you)
Single variable calculus
Multivariable calculus and/or linear algebra (most desirable for you)
In addition, you can check the upper level economics courses for mathematical economics courses.
If you plan to go on to PhD study in economics, upper level math and statistics courses like real analysis, upper level linear algebra, and probability theory are typically suggested.
Run the net price calculator on each college’s web site, but be prepared to be disappointed if you need substantial financial aid.
