Karen spents 450 dollars on monthly bills. Of this total amount, 12% is for phone service,1/10 is for Internet service, and 2/9 is for utilities. If the rest of the total amount is for food, how much does Karen have for food?
I said $130 since I subtract all
(0.12 + 0.1 + 0.2222)450 = 198.9
400 - 199 = $201
I don't think so since the answer is nothing to the choices
A. $144
B. $199
C. $251
D. $277
My answer was only $2.00 off. That can be accounted for by the fact that I used a decimal for the fraction. Using the fraction -- here's the answer.
(0.12 + 0.1)450 = 99
(2/9) * 450 = 900/9 = 100
100 + 99 = 199
To find out how much Karen has for food, we need to calculate the portions of her monthly bills that are allocated to phone service, Internet service, and utilities.
First, let's find the amount spent on phone service:
12% of $450 = (12/100) * $450 = $54
Next, let's find the amount spent on Internet service:
1/10 of $450 = (1/10) * $450 = $45
Now, let's calculate the amount spent on utilities:
2/9 of $450 = (2/9) * $450 = $100
To find the remaining amount allocated for food, we need to subtract the sum of the expenses for phone service, Internet service, and utilities from the total amount of monthly bills:
Total amount spent on bills = $54 + $45 + $100 = $199
Remaining amount for food = Total amount of monthly bills - Sum of expenses for specific services
Remaining amount for food = $450 - $199 = $251
Therefore, Karen has $251 for food.
