Q: A country produces only two goods: computers and bread. In 2017 (the base year), it produced 100 computers at $$\1$$,000$$ each and 10,000 loaves of bread at $$\$$2$$ each. In 2025, it produced 120 computers at $$\1$$,200$$ each and 12,000 loaves of bread at $$\$$2.50$$ each. What is the real GDP in 2025 using 2017 prices?
