Here is all of the relevant info. Looking to solve for C(8) in problem PS5.3.3

Kendall Square Inc makes and sells ramen to the large number of students around MIT. Kendall Square Inc uses the production function F (K, L) = (K + 2L) . Input prices are w = 2 and r = 3 for labor and capital respectively. It operates in a perfectly competitive environment facing a price p = $48, and uses an initial amount of capital K - 12. Compute the firm's short-run cost function. To verify that you have the correct short-run cost function, calculate the short-run cost of producing 8 units of ramen.
