Someone help me please asap I

K= 4 so, 5/4 = 10/8

You will make cross multiplication.

So, we will make 5 x 8 =40, then we will divide 40 by 10 which is equal to 4.

Hope it helps:D

Total = Principal * e^(rate*years)
Total = 100 * 2.718281828^.08*15
Total = 100 * 2.718281828^1.2
Total = 100 * 3.3201169221
Total = 332.01
