Answer:

- 638.42

Step-by-step explanation:

introduction. Per cent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

- 4.5% = - 4.5/100 = - 4.5 ÷ 100 = - 0.045.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by - 4.5% of its value.

Percentage increase = - 4.5% × 14,187.13

New value = 14,187.13 + Percentage increase

Calculate the New Value

New value =

14,187.13 + Percentage increase =

14,187.13 + (- 4.5% × 14,187.13) =

14,187.13 - 4.5% × 14,187.13 =

(1 - 4.5%) × 14,187.13 =

(100% - 4.5%) × 14,187.13 =

95.5% × 14,187.13 =

95.5 ÷ 100 × 14,187.13 =

95.5 × 14,187.13 ÷ 100 =

1,354,870.915 ÷ 100 =

13,548.70915 ≈

13,548.71

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 14,187.13 =

13,548.70915 - 14,187.13 =

- 638.42085 ≈

- 638.42
