1. The given consumption function is $c=10 - 5q$. 2. We need to calculate the value of $c$ for $q=0, 10, 15, 20, 25, 30$. Calculate for each value: 3. For $q=0$, $c = 10 - 5 \times 0 = 10$. 4. For $q=10$, $c = 10 - 5 \times 10 = 10 - 50 = -40$. 5. For $q=15$, $c = 10 - 5 \times 15 = 10 - 75 = -65$. 6. For $q=20$, $c = 10 - 5 \times 20 = 10 - 100 = -90$. 7. For $q=25$, $c = 10 - 5 \times 25 = 10 - 125 = -115$. 8. For $q=30$, $c = 10 - 5 \times 30 = 10 - 150 = -140$. Final answer: The values of $c$ are: - At $q=0$, $c=10$. - At $q=10$, $c=-40$. - At $q=15$, $c=-65$. - At $q=20$, $c=-90$. - At $q=25$, $c=-115$. - At $q=30$, $c=-140$.
