To calculate how much Sara earned last week, we need to consider the charges for each pet and the amount of time she spent pet-sitting.
According to the table, Sara charges $200 for sitting one dog and $150 for sitting one cat. Last week, she sat for one dog and two cats.
To calculate the total amount earned, we can use the following expression:
Total earnings = (Number of dogs * Charge per dog) + (Number of cats * Charge per cat)
In this case, Sara sat for one dog and two cats, so the expression becomes:
Total earnings = (1 * $200) + (2 * $150)
Simplifying the expression, we have:
Total earnings = $200 + $300
Total earnings = $500
Therefore, Sara earned $500 last week.
Now, let's evaluate the expression to find out how much Sara earned if she sat for 8 hours for the dog.
To calculate the earnings for a specific number of hours, we need to consider the charge per hour for the dog. However, the given information does not provide the charge per hour for the dog. Therefore, we cannot accurately evaluate the expression for this specific scenario.
