Question

On Monday Ethan sends an email to 3 friends the next day each of the 3 friends forward the email to 3 friends and so on as shown below how many people received the email by Thursday?

Answer 1

The answer is 12 people. The amount of days that pass from Monday to Thursday is 3, but you have to include Monday since Ethan sent 3 that day. Since three emails were sent out each of the four days, you would need to multiply 3 by 4. 3 x 4 = 12

Answer 2

its 13 people by Thursday

Explanation:

if Ethan send the email to 3 people on Monday that means he also had the email on Monday so that's 3+1=4 and the next day would be Tuesday that's 3 more people and 3+4=7 so by tuesday there would be 7 people then theres Wednesday that's 3 more people if you do 3+7=10 that's 10 by Wednesday then theres thursday 3 more people 10+3=13 that's how I got my answer to you
