1. **State the problem:** Clara needs to pay a security deposit that equals the first and last month's rent plus $75 per pet. She has 1 dog and 1 cat. 2. **Identify the known values:** - Monthly rent = 975 - Number of pets = 2 (1 dog + 1 cat) - Pet fee per pet = 75 3. **Write the formula for the security deposit:** $$\text{Security Deposit} = 2 \times \text{Monthly Rent} + (\text{Number of Pets} \times \text{Pet Fee})$$ 4. **Substitute the known values:** $$\text{Security Deposit} = 2 \times 975 + (2 \times 75)$$ 5. **Calculate each part:** $$2 \times 975 = 1950$$ $$2 \times 75 = 150$$ 6. **Add the parts together:** $$1950 + 150 = 2100$$ 7. **Final answer:** Clara will owe **2100** for her security deposit.
