Joey has already taken 3 pictures at home, and he expects to take 1 picture during every
day of vacation. How many days will Joey have to spend on vacation before he will have
taken 13 pictures?

Respuesta :

As he’s already taken 3, he only needs 10 more photos for 13. So he needs 10 days to get the rest
