Answer:
$600
Step-by-step explanation:
Total entrance company A= 110 + daily sales amount x 7%
Total entrance Company B = 80 + daily sales amount x 12%
The point with the same entrance for both companies could be obtained matching both equations:
110+daily sales amount x 7% = 80 + daily sales amount x 12% ,
clearing the variable (daily sales amount) :
daily sales amount= (110-80) / ( 12%-7% ) = 30 /5% = $600
