To determine Lauren's profit, we need to calculate her total costs and then subtract that from her total revenue. 1. **Known Conditions:** - Total Revenue (R) = \$111,000 - Rent (R_r) = \$48,000 - Labor Costs (C_l) = \$43,000 - Variable Costs (C_v) = \$19,000 2. **Calculate Total Costs (C):** \[ C = R_r + C_l + C_v \] Substituting the known values: \[ C = 48000 + 43000 + 19000 \] Let's calculate this step by step: - First, add the rent and labor costs: \[ 48000 + 43000 = 91000 \] - Now, add the variable costs: \[ 91000 + 19000 = 110000 \] So, the total costs (C) are: \[ C = 110000 \] 3. **Calculate Profit (P):** \[ P = R - C \] Substituting the values: \[ P = 111000 - 110000 \] Performing the subtraction: \[ P = 1000 \] 4. **Conclusion:** Lauren earned a profit of \$1,000. Thus, the correct answer is: **OB) earned a profit of \( \$ 1,000 \).**
