Carolina values consumption (c) and leisure (L). She has 16 units of time to divide between working or enjoying leisure. For each hour worked she receives 10 units of the consumption good. Suppose that Carolina's utility function is given by U(c, L) = cL. What is Carolina's budget constraint?
a) c = 10L
b) c = 16L
c) c + 10L = 160
d) c + 10L = 16
