The Intertemporal Budget Constraint Is Written As:
A) B) C) $c _ { \text {today } } + c _ { \text {future } } = f _ { \text {today } } ( 1 + R ) + y _ { \text {today } } + y _ { \text {future } }$

The intertemporal budget constraint is written as:

A) $c _ { \text {today } } + \left( c _ { \text {future } } / 1 + R \right) = f _ { \text {today } } + y _ { \text {today } } + \left( y _ { \text {fature } } / 1 + R \right)$

B) $\left[ \left( c _ { \text {today } } / ( 1 + R ) \right] + c _ { \text {future } } = f _ { \text {today } } + \left[ y _ { \text {today } } / ( 1 + R ) \right] + y _ { \text {future } } \right.$
C) $c _ { \text {today } } + c _ { \text {future } } = f _ { \text {today } } ( 1 + R ) + y _ { \text {today } } + y _ { \text {future } }$
D) $u \left( c _ { \text {todey } } \right) + \beta u \left( c _ { \text {future } } \right) = f _ { \text {todey } } + \gamma _ { \text {todey } } - \gamma _ { \text {future } }$
E) $c _ { \text {todey } } + y _ { \text {today } } = \left( c _ { \text {future } } / 1 + R \right) + \left( \gamma _ { \text {future } } / 1 + R \right)$
