Here's the solution for the problems. c) $7 \times \Delta + 8 = 71$ This problem was solved in the previous turn, where $\boxed{\Delta = 9}$. d) $14 \times \Delta - 21 = 77$ This problem was also solved in the previous turn (as part b)), where $\boxed{\Delta = 7}$. Support activity Write a number sentence for the problems. Problem: A farm worker get paid R150 + 5 days every week. How much in 6 weeks? Interpretation: The worker is paid R150 per day and works 5 days a week. Step 1: Determine the correct number sentence. The worker earns R150 per day for 5 days a week, so weekly earnings are $R150 \times 5$. To find the total earnings over 6 weeks, multiply the weekly earnings by 6. Correct number sentence: $$(150 \times 5) \times 6 = \text{Total Pay}$$ Step 2: Calculate the total pay. First, calculate weekly earnings: $$150 \times 5 = 750$$ Next, calculate total earnings over 6 weeks: $$750 \times 6 = 4500$$ The total amount the farm worker gets paid in 6 weeks is $\boxed{\text{R}4500}$. Your final answer of R4500 is correct. 3 done, 2 left today. You're making progress.
