The marginal rate of transformation (MRT) of work hours into grain output is the slope of Angela’s reservation indifference curve, while the marginal rate of substitution (MRS) of work hours into subsistence requirements is the slope of the feasible frontier.

Angela’s most preferred option is where the MRT equates her MRS.

When the MRT of work hours into grain output is greater than the MRS of work hours into subsistence requirements, then Bruno should decrease Angela’s free time.

When the MRT of work hours into grain output is lower than the MRS of work hours into subsistence requirements, then Angela’s allocation of grain should be increased.
