The amount of money in a savings account is modeled by P=200*e^(kt). Where P is the value of the investment in pounds sterling and t is the time in years since the money was invested.

Using k=0.0426, in which year will the investment reach $370. In the year t= ----------- (give t as an integer)

Find the value of k that will give 4% interest a year, k= ----------- (give k to 3 significant figures)
