The learning curve formula is Y = A * X^b, where Y is the time for the Xth unit, A is the time for the first unit, X is the unit number, and b is the learning curve exponent (log of the learning rate/log of 2). For a 75% learning curve, b = log(0.75)/log(2). Plugging in the values, Y = 350 * 15^b ≈ 113.75 days.
