Answer:
$600
Step-by-step explanation:
If the level of disposable income is $1,000, then the level of saving is given by the equation C = $1,000 + 0.60YD.
Substituting the value of disposable income, we get:
C = $1,000 + 0.60YD
= $1,000 + 0.60 * $1,000
= $1,000 + $600
= $1,600
Therefore, the level of saving is $1,600 - $1,000 = $600.
