Respuesta :
its 13 people by Thursday
Step-by-step 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
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
