Answer

Explanation:

Step1: Calculate number of visitors in week 2

The number of visitors in week 2 is 10% more than week 1. So we use the formula $N_2=N_1\times(1 + 0.1)$, where $N_1 = 3200$. $N_2=3200\times(1 + 0.1)=3200\times1.1 = 3520$

Step2: Calculate number of visitors in week 3

The number of visitors in week 3 is 15% more than week 2. So we use the formula $N_3=N_2\times(1 + 0.15)$, where $N_2 = 3520$. $N_3=3520\times(1 + 0.15)=3520\times1.15=4048$
