If I get 10 cent a day and I need to get to 13 dollars how many days will it take?

It will take 10 days to get one dollar, so it would take 130 days to make 13 dollars

We know that 100 cents is 1 dollar so we need to find how many cents is 13 dollars.

100 cents x 13 dollars = 1300 cents

Then we divide 1300 by 10 to get how many days it will take to get 13 dollars

so ...

1300 divided by 10 = 130

It will take 130 days to get 13 dollars
