1. **State the problem:** Monique works for $h$ hours as a lifeguard earning 12 per hour and also earns 20 for dog sitting. We need to find an expression representing her total earnings this week. 2. **Understand the components:** - Earnings from lifeguard work: $12 \times h = 12h$ - Earnings from dog sitting: 20 (a fixed amount) 3. **Form the expression:** Total earnings = earnings from lifeguard + earnings from dog sitting 4. **Write the expression:** $$12h + 20$$ 5. **Check other options:** - $12h + 20h = 32h$ (incorrect, dog sitting is a fixed amount, not per hour) - $12h + 10$ (incorrect, dog sitting is 20, not 10) - $10h + 20$ (incorrect, lifeguard rate is 12, not 10) **Final answer:** $$12h + 20$$
