<h3>The value after 4 years is $ 2244.16</h3>

<em><u>Solution:</u></em>

<em><u>The decreasing function is given as:</u></em>

y = a(1-r)^t

Where,

y is final value

a is initial value

r is decreasing rate in decimal

t is number of years

From given,

a = 3000

t = 4 years

r = 7 \% = \frac{7}{100} = 0.07

<em><u>Substituting the values we get,</u></em>

y = 3000(1-0.07)^4\\\\y = 3000 \times 0.93^4\\\\y = 3000 \times 0.74805201\\\\y = 2244.15603\\\\y \approx 2244.16

Thus the value after 4 years is $ 2244.16
