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

anas.p · Answer

150 after 3 weeks you have 120
So 150-120=30
30 in 3 weeks 30/3=1
Again From 120 you have 100 left after 2 weeks
So 120-100=20
20 in 2 weeks 20/2=10
