5000 people visited book fair in 1st week. Decreased by 10% in the 2nd week and increased by 10% in the 3rd week. How many people visited the book fair during the 3 weeks?

Question

5000 x 10% 500

5000 - 500 = 4500

4500 x 10% = 450

4500 + 450 = 4950

Do I add 5000, 4500 and 4950 altogether?

Answer 1

Week 1: 5000

Week 2: 4500 [5000 - 0.10*5500]

Week 3: 4950 [4500 + 0.10*4500]

TOTAL 14450
