$Y=C+I+G$

$C=120+0\mathrm{.}8(Y-T)$

$I=500-50T$

$G=150$

$T=125$

where $Y$ is GDP$,C$ is consumption, I is investment, $G$ is government purchases, $T$ is taxes, and $r$ is the interest rate. If the economy were at full employment $($that is$,$ at the natural rate of output$),$ GDP would be $$2,850.$

Identify the equation$($s$)$ each of the following statements describes. Check all that apply.
