Question

r(1) = 3000 - 500 * 1.4^1

Answer 1

To calculate \( r(1) \), you can substitute \( t = 1 \) into the equation:

\[
r(1) = 3000 - 500 \times 1.4^1
\]

Now, calculate \( 1.4^1 \):

\[
1.4^1 = 1.4
\]

Now, substitute that back into the equation:

\[
r(1) = 3000 - 500 \times 1.4
\]

Next, calculate \( 500 \times 1.4 \):

\[
500 \times 1.4 = 700
\]

Now, substitute that value back into the equation:

\[
r(1) = 3000 - 700
\]

Finally, calculate \( r(1) \):

\[
r(1) = 2300
\]

So, \( r(1) = 2300 \).
