how do I find the new entertainment spending amount and how much money he is adding to his grocery budget?

Question

Jarius is a student working on his budget. In going through his spending for the previous month he found that he spent $252 on groceries, $55 on his cell phone bill, and $49 on entertainment. He made no other purchases.

 

What were the percentages for his spending on each of Jarius's budget categories?

Category	Amount	Percentage (Round to one decimal place)
Groceries	$252	70.8   %
Phone	$55	15.4   %
Entertainment	$49	13.8   %

 

Jarius wants to reduce his entertainment percentage to be 11.8% of his total spending. He wants to add the money he will save in his entertainment spending into his grocery budget.

 

What should his new entertainment spending amount be to accomplish his goal and how much money will he add to his grocery budget each month by reducing his entertainment amount?

 

Answer 1

1.) Find the total amount spent by adding up the middle column:

Total Amount Spent = 252 + 55 + 49 = 356.

2.) Find the percentage of the total amount found from the previous step:

New Entertainment Budget = 0.11 * 356 = 39.16

3.) To find the amount going to his grocery budget, subtract the previous entertainment budget from the new budget from the previous step:

Saved Amount = 49 - 39.16 = 9.84

Answer 2

0.138b = 49

b = 355

He will be dropping 2%.

0.02(355) = $7
