2. What is the final figure when a sum £2,000 is increased by 18%?​

Answer 1

Answer:

1) 76,500

Steps:

85,000 - Percentage decrease =

85,000 - (10% × 85,000) =

85,000 - 10% × 85,000 =

(1 - 10%) × 85,000 =

(100% - 10%) × 85,000 =

90% × 85,000 =

90 ÷ 100 × 85,000 =

90 × 85,000 ÷ 100 =

7,650,000 ÷ 100 =

76,500

2) 2,360

Steps:

2,000 + Percentage increase =

2,000 + (18% × 2,000) =

2,000 + 18% × 2,000 =

(1 + 18%) × 2,000 =

(100% + 18%) × 2,000 =

118% × 2,000 =

118 ÷ 100 × 2,000 =

118 × 2,000 ÷ 100 =

236,000 ÷ 100 =

2,360
