If I would put away...?

$ 1042, there are 104.28 weeks in two years, and you put away every 2nd week means 52.14 weeks. So 52.14 * 20 = $ 1042

52 weeks per year means you would put away money 26 times a year (52 weeks/2 weeks). For two years that makes 52 times. Just multiply 20 by 52 to get your answer.

52 weeks in a year. So 52 times over the course of two years.

52*20=$1040

If it's in a bank account it will gain interest and make it even more (though not much more if it's only a couple years)

It's called excell.... very handy!

But to answer your question

52 x $20 = $1,040
