Final answer:
To calculate Charlotte's earnings after receiving both raises, find the amount of each raise and add them to her monthly salary.
Step-by-step explanation:
To calculate the amount of money Charlotte will earn after both raises, we first need to find the amount of each raise.
First, we find the 9% raise: 9% of $2,120 = $190.80.
Then, we find the 5% raise: 5% of ($2,120 + $190.80) = $115.50.
Finally, we add both raises to Charlotte's monthly salary: $2,120 + $190.80 + $115.50 = $2,426.30.
