Decrease = initial price - final price

% decrease = [ (initial price - final price) / initial price ] *100

% decrease =[ (2.89 - 2.83) / 2.89] * 100 = 2.08, which can be rounded to 2.1

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

$\int_{0}^{5}3000(t+2).dt$

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

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

= $\$ 67500$
