To evaluate the expression \( r(3) = 3000 - 500 \times 1.4^3 \), we will first calculate \( 1.4^3 \), then multiply by 500, and finally subtract the result from 3000.
1. Calculate \( 1.4^3 \):
\[
1.4^3 = 1.4 \times 1.4 \times 1.4 = 2.744
\]
2. Multiply by 500:
\[
500 \times 2.744 = 1372
\]
3. Subtract from 3000:
\[
r(3) = 3000 - 1372 = 1628
\]
Therefore, the value of \( r(3) \) is \( 1628 \).
1. Calculate \( 1.4^3 \):
\[
1.4^3 = 1.4 \times 1.4 \times 1.4 = 2.744
\]
2. Multiply by 500:
\[
500 \times 2.744 = 1372
\]
3. Subtract from 3000:
\[
r(3) = 3000 - 1372 = 1628
\]
Therefore, the value of \( r(3) \) is \( 1628 \).
