Answer 1

Answer:

a)original weekly expenses =2500

b)weekly income=3125

Step-by-step explanation:

let original weekly expenses be X

new weekly expenses =2125

According to the question

New weekly expenses = 15%less than original weekly expenses

Therefore 2125=x - 15% of x

2125=85/100x

2125*100/85=x

212500/85=x

2500=x

Therefore original weekly expenses is 2500

Now ,original weekly expenses is 80% of weekly income

Therefore 2500=80% of weekly income

2500*100/80=weekly income

3125= weekly income
