she saves 10 per week.......after 4 weeks, she had 90

so if she started with nothing, after 4 weeks she would have 40.....but for her to have 90, she would have had to have started with (90 - 40) = 50.

Think about it....she starts with 50....and then saves 10 for 4 weeks giving her 40......and now she has 40 + 50 = 90

so ur answer is : Roberta had $ 50 before she started to save money each week
