In a simplified economic model, total planned spending (aggregate demand, AD) is the sum of consumption (C) and planned investment (I). If the consumption function is given by the equation C = 250 + 0.6Y, where Y is income, and planned investment is fixed at a value of 150, which of the following equations correctly represents the aggregate demand function for this economy?

Autonomous Demand
In a simplified economic model, total planned spending (aggregate demand, AD) is the sum of consumption (C) and planned investment (I). If the consumption function is given by the equation C = 250 + 0.6Y, where Y is income, and planned investment is fixed at a value of 150, which of the following equations correctly represents the aggregate demand function for this economy?
Analyzing Components of Aggregate Demand
Calculating Total Planned Spending
Consider an economy where total planned spending is the sum of consumption and planned investment. If the consumption behavior is described by a standard linear function dependent on income, and planned investment is a fixed amount, a decrease in this fixed amount of investment will cause the total planned spending function to shift upwards for any given level of income.
In a simplified economic model where total planned spending is the sum of consumption and a fixed amount of investment, the resulting aggregate demand (AD) function is given by the equation: . Match each component from the equation to its correct economic description.

In a simplified economy, total planned spending (aggregate demand, AD) is the sum of consumption (C) and planned investment (I). The aggregate demand function is given by the equation AD = 500 + 0.75Y, where Y is income. If planned investment is a fixed amount of 200, which of the following equations correctly represents the consumption function for this economy?
Critique of the Simplified Aggregate Demand Model
In a simplified economy where total planned spending is the sum of consumption and planned investment, the consumption function is given by C = 100 + 0.8Y and planned investment (I) is a fixed amount of 50. If the current level of income (Y) is 1,000, the portion of total planned spending that is induced by income is ____.
