Answer:

i). \$ 7500

ii).\$ 67500

Step-by-step explanation:

Given in the question-

Saving rate is s(t)= 3000(t+2)

We know that savings in the 1st year can be calculated as

    \int_{0}^{1}3000(t+2).dt

    3000\left [ \frac{t^{2}}{2}+2t \right ]_0^1

    3000\left [ \frac{1}{2}+2 \right ]

 = \$ 7500

So savings in the first 5 years can be calculated as

     \int_{0}^{5}3000(t+2).dt

    3000\left [ \frac{t^{2}}{2}+2t \right ]_0^5

    3000\left [ \frac{25}{2}+5 \right ]

 = \$ 67500
