Equilibrium Expenditure

Question

In the global economy, when the price level is 100, aggregate planned expenditure would be $10 trillion if real GDP were zero; when the price level is 90, aggregate planned expenditure would be $11 trillion if real GDP were zero; and when the price level is 110, aggregate planned expenditure would be $9 trillion if real GDP were zero. For each $1 increase in real GDP, aggregate planned expenditure increases by 75cents, and this relationship between expenditure plans and real GDP is the same at every price level.

Calculate equilibrium expenditure at price levels of 90, 100, and 110.

i think there is something missing from your question may be its real gdp growth rather than real GDP

if u can clear that confusion then i may be able to answer your question
