Answer :
Using the percentage concept, it is found that 40% of Alberto’s income is used to pay for his rent and groceries.
What is a percentage?
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
In this problem:
- Alberto’s monthly income is $3,200, hence b = 3200.
- He spends 896 + 384 = $1280 in rent and groceries, hence a = 1280.
Then, the percentage is given by:
[tex]P = \frac{1280}{3200} \times 100\% = 40\%[/tex]
