Detailed Solution
Download Solution PDFApproximate each term by rounding to the nearest whole number:
49.95 ≈ 50
12.12 ≈ 12
19.98 ≈ 20
7.95 ≈ 8
1.98 ≈ 2
60.05 ≈ 60
Calculate each component:
First term: 50 × 12 = 600
Second term: 20 × 8 = 160
Third term: 2 × 60 = 120
Combine the terms:
600 - 160 - 120 = 320
Thus, the correct answer is 320.
