Question

If an animal eats 300 pounds a day.
How many pound do they eat a week and then
Write an expression to answer
There are 52 weeks in a year. How much does it cost to keep one adult for one year?

Answer 1

To calculate how many pounds an animal eats in a week, we can use the daily consumption and multiply it by the number of days in a week.

1. **Daily Consumption**: 300 pounds
2. **Days in a Week**: 7 days

### Pounds Eaten in a Week:
To find the weekly consumption, we use the expression:

\[
\text{Weekly Consumption} = \text{Daily Consumption} \times 7
\]

Substituting the daily consumption:

\[
\text{Weekly Consumption} = 300 \, \text{pounds/day} \times 7 \, \text{days} = 2100 \, \text{pounds/week}
\]

### Pounds Eaten in a Year:
To find the annual consumption, we multiply the weekly consumption by the number of weeks in a year:

\[
\text{Annual Consumption} = \text{Weekly Consumption} \times 52
\]

Substituting the weekly consumption:

\[
\text{Annual Consumption} = 2100 \, \text{pounds/week} \times 52 \, \text{weeks} = 109200 \, \text{pounds/year}
\]

### Cost of Keeping One Adult for One Year
To determine the yearly cost of feeding the animal, you'll need to specify the cost per pound of food. Let's suppose the cost is \( C \) dollars per pound.

The total cost for one year would then be calculated as follows:

\[
\text{Yearly Cost} = \text{Annual Consumption} \times C = 109200 \, \text{pounds/year} \times C \, \text{(cost/pound)}
\]

So, if you want to relate everything into one expression, the total cost can be expressed as:

\[
\text{Yearly Cost} = 109200C
\]

Where \( C \) is the cost per pound of food.
