Final answer:
Mr. Thompson's yearly grocery expense is $4,836. His budget for food and rent per year is $16,836. His yearly income is $12,150. The estimated percentage of rent to his income is 26% and the estimated percentage of food to his income is 40%.
Step-by-step explanation:
To calculate the average yearly grocery expense, Mr. Thompson estimates his monthly expense to be $372 (2 x $186, assuming he spends the same amount twice a month). However, since there are more than 24 two-week periods in a year, he revises his estimate using 26 x $186 to get a yearly estimate of $4,836. Therefore, Mr. Thompson's yearly grocery expense is $4,836.
To calculate the budget for food and rent, we add Mr. Thompson's annual rent ($12,000) to his annual grocery expense ($4,836) to get a total of $16,836.
If Mr. Thompson receives $506.28 twenty-four times a year, his yearly income is $12,150.
The estimated percentage of rent to Mr. Thompson's income is 26% (annual rent of $12,000 divided by yearly income of $12,150). The estimated percentage of food to Mr. Thompson's income is 40% (annual grocery expense of $4,836 divided by yearly income of $12,150).
