Final answer:
The consumption level, given the disposable income of $14,000 using the formula C = $7,000 + 0.05 Yd, is found to be $7,700.
Step-by-step explanation:
The student asked about the level of consumption given the formula C = $7,000+ 0.05 Yd and a level of disposable income (Yd) of $14,000. To calculate the consumption level, we use the given function by plugging in the value of Yd:
C = $7,000 + 0.05 Ă— $14,000
C = $7,000 + $700
C = $7,700
Therefore, the correct level of consumption is $7,700, which corresponds to option c).
