0.05X=10
X=200
it should be that

Answer 2

Mary's weekly income is $200.

Explanation:

Let x be the Mary's weekly income.

It is given that Mary spends only 5% of her weekly income on entertainment.

Total amount she spends on entertainment is

`Expense=x* (5)/(100)=0.05x`

It is also given that she usually spends about $10.00.

`0.05x=10`

Divide both sides by 0.05.

`(0.05x)/(0.05)=(10)/(0.05)`

`x=200`

Therefore, Mary's weekly income is $200.
