Question

Brent spends $ 420 on his monthly bills. Of this amount, 15 % is for utilities, 1/5 is for Internet service, and 1/7 is for phone service. If the rest of the total amount is for food, how much money does Brent have for food?

Answer 1

To find out how much money Brent has for food, we need to subtract the amounts spent on utilities, Internet service, and phone service from the total monthly bills. Brent has $213 for food.

Step-by-step explanation:

To find out how much money Brent has for food, we need to subtract the amounts spent on utilities, Internet service, and phone service from the total monthly bills.

First, we calculate the amount spent on utilities by multiplying the total bills ($420) by 15%: $420 * 0.15 = $63.

Next, we calculate the amount spent on Internet service by dividing the total bills ($420) by 5: $420 / 5 = $84.

Then, we calculate the amount spent on phone service by dividing the total bills ($420) by 7: $420 / 7 = $60.

Finally, we subtract the amounts spent on utilities, Internet service, and phone service from the total bills to find the amount Brent has for food: $420 - $63 - $84 - $60 = $213.

Therefore, Brent has $213 for food.

Answer 2

Answer: $213

Step-by-step explanation:

First find out how much is spent on the other things:

Utilities

= 15% * 420

= $63

Internet services

= 1/5 * 420

= $84

Phone service

= 1/7 * 420

= $60

The amount left for food is therefore:

= 420 - money spent on other things

= 420 - 63 - 84 - 60

= $213
