Please help on math.

Answer:
[tex]\fbox{625 \: dollars }[/tex]
Step-by-step explanation:
Given:
from circular graph,
Savings by Oliver's = 25% of Total budget
Monthly budget = $ 2500
To find:
How much money does Oliver save?
Solution:
From diagram we came to know that,
Oliver's saving is 25% of total monthly budget.
Hence the money he saves each month will be 25% of $2500(Monthly budget)
To calculate the X percent of any given real number multiply the number with X and divide it by 100.
[tex] \sf \hookrightarrow \: 25 \% \: of \: 2500 \\ \sf \hookrightarrow 2500 \times \frac{25}{100} \\ \sf \hookrightarrow 2500 \times \cancel\frac{25}{100}_4 \\ \sf \hookrightarrow \: \frac{2500}{4} \\ \sf \hookrightarrow \cancel{\frac{2500}{4}} \: ^{625} \\ \sf \hookrightarrow \fbox{625 \: dollars }[/tex]
625$ does Oliver saves each month.
