Answer:
$5,333.33
Explanation:
If the a month spent on rent is a percentage of the monthly budget of the Fernando family, it means that the product of the percentage and the monthly budget gives the amount spent on rent.
Let the monthly budget be T (measured in $). Given that the family spends $800 per month on rent and this is 15% of their monthly budget, it means that
15% * T = 800
T = 800/15%
= 800 * 20/3
= $5,333.33
The family's monthly budget is $5,333.33
