Answer:
Mary's weekly income is $200.
Step-by-step 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
[tex]Expense=x\times \frac{5}{100}=0.05x[/tex]
It is also given that she usually spends about $10.00.
[tex]0.05x=10[/tex]
Divide both sides by 0.05.
[tex]\frac{0.05x}{0.05}=\frac{10}{0.05}[/tex]
[tex]x=200[/tex]
Therefore, Mary's weekly income is $200.
