Question

Evaluate 20% of 450 + 40% of 280:

Answer 1

Answer:

472

Step-by-step explanation:

20% of 450 = $\frac{20}{100}$ × 450

                    = 20 × 18

                    = 360

40% of 280 = $\frac{40}{100}$ × 280

                    = 8 × 14

                    = 112

∴ 20% of 450 + 40% of 280 = 360 + 112

                                               = 472
