Question

7. Georgina balances her budget by using this plan. For every $100 she earns, she budgets $10 for charity, $20 for savings, $20 for books, and $50 for other expenses. What amount does she give to charity each week if her income is $500 per week? A. $500 B. $5 C. $250 D. $50

Answer 1

to solve this question, we can find the percentage she gives to charity o every dollar she earns

if she earns $100, she gives $10 to charity. let's find the percentage on this.

`(10)/(100)*100=0.1*100=10\text{ \%}`

from the calculation, she gives 10% of are earnings to charity.

now we can find 10% of $500 to solve this question.

`\begin{gathered} 10\text{ \% of \$500} \\ (x)/(500)=(10)/(100) \\ (x)/(500)=0.1 \\ x=0.1*500 \\ x=50 \end{gathered}`

from the calculations above, she gives out $50 on charity weekly from her $500 income.
