Answer: Disposable income = $100.

Step-by-step explanation:

Since we have given that


C=\$25+0.75Y

And, average propensity to consume = 1

i.e. APC = 1

As we know the formula of APC ,


APC=(C)/(Y)=1\\\\\implies C=Y

So, our equation becomes,


Y=\$25+0.75Y\\\\Y-0.75Y=\$25\\\\0.25Y=\$25\\\\y=(25)/(0.25)\\\\Y=100

Hence, Disposable income = $100.
