See the spending multiplier worked out with your class numbers

About this exercise

AP Macro's spending multiplier confuses you. Get exactly 3 numbered lines: the multiplier calculation with the numbers shown, the total change in GDP with the numbers shown, and one sentence on what it means for the town, plain text, under 70 words. Use the corrected MPC from Mr. Farouk's announcement.

Common mistakes when you ask AI for this

• Asking for an explanation. The AI explains the idea in words and may reuse the slide's old numbers. Try: Ask for the math: "Show each calculation with the numbers."
• Missing the correction. The slide's MPC and the corrected one are both in your notes. Try: Add: "Use the corrected MPC of 0.75."
• Not saying how many lines. The AI picks its own number, and it usually picks more lines than you need. Try: Be exact: "Exactly 3 numbered lines."
• Skipping the meaning. Numbers alone don't answer your real question: how $2 million becomes more. Try: Add: "End with one sentence on what it means for the town."
• Trusting the AI to count words. AI is bad at counting. Ask for a total and it often lands 20% over. Try: Cap each line: "each under 20 words."
• Forgetting where it will be read. AI formats for a screen, with bold and headings that show up as stray symbols in your notes. Try: Say: "Plain text, no bold, no headings."
