Suri saved $150 of her paycheck the first week she worked and $50 of her paycheck each week after the first week. How many weeks did it take Suri to save a total of $1,000?

150  + 50N  =  1000      where N is the number of weeks we are seeking


Subtract 150  from both sides


50N   =  850       divide both sides by 50


N  =  17  weeks
