Jim currently has​ $\$1,250$ in his bank account and Sally has​ $\$1,400$ in her bank account. Jim deposits​ $\$27.50$ per week and Sally deposits​ $\$20$ per week into her account. After how many weeks will they have the same amount of​ money?

1250 + 27.50 W =   1400 + 20W

 

(27/50 - 20)W = 1400  -1250

 

7.50W  =  150

 

W =  150  /  7.50    =  20   (weeks)
