please help i dont get it? For your birthday you are given $150. After three weeks you have $120. Two weeks after that, you have $100. If the amount that you spend each week remains constant, how much will you have 10 weeks after your birthday? (1 point)

In 3 weeks you are spending $30
In 2 weeks you are spending $20
So you are spending $10 a week
You received $150 for your birthday.
10 weeks later you will have spend $100 ($10*10)
So you will have $150-$100 left that is $50.
this is stupid but 50-10=40 so how are you only spending 10 a week
150 after 3 weeks you have 120
30 in 3 weeks 30/3=1
Again From 120 you have 100 left after 2 weeks
20 in 2 weeks 20/2=10
