Answer 1

Find out the what is the number of weeks that have passed since since jeffrey had $250 .

To prove

Let us assume that the number of weeks be x .

As given

Jeffrey has $250 in the bank.

Each week he takes out $25.After a few weeks jeffrey has $87.50 left in the bank.

Than the equation becomes

87.50 = 250 - 25 x

87.50 = 250 - 25x

250 - 87.50 = 25x

162.5 = 25x

`x = (162.5)/(25)`

x = 6.5 weeks

Therefore it take 6.5 weeks (approx) that have passed since jeffrey had $250 .
