Answer:
The amount of Lantz's operating revenue is $734,000
Explanation:
The computation of the operating revenue is shown below:
= Total cash sales + Total credit sales
= $255,000 + $479,000
= $734,000
Since we have to compute the operating revenue, so we considered only revenue part not expenses part
The other information which is mentioned in the question is not being considered because it is related to the operating expenses. So, ignored it.
