hello
the question presented here deals with percentages
the percentage of a variable is the ratio of the value of that function to the total variable multiplied by 100
total categories = food + rent + other +fun
sum the value of everything

she spends a total of $1600 for that month
the percentage of her total spending spent on rent = (rent / total spending) * 100


the percentage of her monthly spending spent on rent is 27.75%
