A student must choose a program of four courses from a menu of courses consisting of English, Algebra, Geometry, History, Art, and Latin. This program must contain English and at least one mathematics course. In how many ways can this program be chosen?

$ \textbf{(A)}\ 6\qquad\textbf{(B)}\ 8\qquad\textbf{(C)}\ 9\qquad\textbf{(D)}\ 12\qquad\textbf{(E)}\ 16$
To solve this problem, we need to consider the constraints: the program must contain English and at least one mathematics course (Algebra or Geometry). We will break down the problem step by step.

1. **Select English:**
   Since English is a required course, there is only 1 way to select English.

2. **Select at least one mathematics course:**
   We have two mathematics courses: Algebra and Geometry. We need to consider the following cases:
   - Case 1: Select exactly one mathematics course.
   - Case 2: Select both mathematics courses.

3. **Case 1: Select exactly one mathematics course:**
   - We have 2 ways to choose one mathematics course (Algebra or Geometry).
   - After selecting English and one mathematics course, we need to choose 2 more courses from the remaining 4 courses (excluding the selected mathematics course and English). The remaining courses are: History, Art, Latin, and the other mathematics course.
   - The number of ways to choose 2 courses from 4 is given by the binomial coefficient:
     \[
     \binom{4}{2} = \frac{4!}{2!(4-2)!} = \frac{4 \times 3}{2 \times 1} = 6
     \]
   - Therefore, the total number of ways for this case is:
     \[
     2 \times 6 = 12
     \]

4. **Case 2: Select both mathematics courses:**
   - There is only 1 way to select both mathematics courses (Algebra and Geometry).
   - After selecting English and both mathematics courses, we need to choose 1 more course from the remaining 3 courses (History, Art, and Latin).
   - The number of ways to choose 1 course from 3 is given by the binomial coefficient:
     \[
     \binom{3}{1} = 3
     \]
   - Therefore, the total number of ways for this case is:
     \[
     1 \times 3 = 3
     \]

5. **Total number of ways:**
   - Adding the number of ways from both cases, we get:
     \[
     12 + 3 = 15
     \]

The final answer is $\boxed{15}$
