Answer 1

Answer:  The total number of visitors in first 8 weeks is 12750.

Step-by-step explanation:  Given that the number of visitors to a website in the first week is 50. The number of visitors each week is double the number of visitors the previous week.

We are to find the total number of visitors to the website in the first 8 weeks.

Number of visitors in 1st week = 50.

Number of visitors in 2nd week = 50 × 2 = 100.

Number of visitors in 3rd week = 100 × 2 = 200.

Number of visitors in 4th week = 200 × 2 = 400.

Number of visitors in 5th week = 400 × 2 = 800.

Number of visitors in 6th week = 800 × 2 = 1600.

Number of visitors in 7th week = 1600 × 2 = 3200.

Number of visitors in 8th week = 3200 × 2 = 6400.

Therefore, the total number of visitors in the first 8 weeks will be

$50+100+200+400+800+1600+3200+6400\\\\=12750.$

Thus, the total number of visitors in first 8 weeks is 12750.
