Answer:
a. $164,000
Step-by-step explanation:
The computation of the Altoon Manufacturing's sales for the year until the flood is given below:
= Cash collections + ending receivables - opening receivables
= $158,000 + $25,000 - $19,000
= $164,000
hence, the Altoon Manufacturing's sales for the year until the flood is $164,000
Therefore the first option is correct
