Question

decrease £19064.67 by 19.5%

Answer 1

Answer:

- 3,717.61

Step-by-step explanation:

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

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

19.5% = 19.5/100 = 19.5 ÷ 100 = 0.195.

100% = 100/100 = 100 ÷ 100 = 1.

Decrease number by 19.5% of its value.

Percentage decrease = 19.5% × 19,064.67

New value = 19,064.67 - Percentage decrease

Calculate the New Value

New value =

19,064.67 - Percentage decrease =

19,064.67 - (19.5% × 19,064.67) =

19,064.67 - 19.5% × 19,064.67 =

(1 - 19.5%) × 19,064.67 =

(100% - 19.5%) × 19,064.67 =

80.5% × 19,064.67 =

80.5 ÷ 100 × 19,064.67 =

80.5 × 19,064.67 ÷ 100 =

1,534,705.935 ÷ 100 =

15,347.05935 ≈

15,347.06

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 19,064.67 =

15,347.05935 - 19,064.67 =

- 3,717.61065 ≈

- 3,717.61
