Evaluate: 840.03 + (7.99)^3 = 90.03% of 599.99 + 37.99

1. 31
2. 28
3. 37
4. 24

Correct answer: 28

Solution

Approximating the values gives \((7.99)^3 \approx 8^3 = 512\) and \(90.03\%\) of \(599.99 \approx 90\%\) of 600 = 540. Then the expression becomes about 840 + 512 - 540 - 38, which is close to 28. Hence the answer is 28.
