You can put this solution on YOUR website!
Let h= the number of hours store is open
Let S= total sales in dollars
The stores will sell $66,500 per hour
S+=+66500h
I must find when S+=+2500000, so
2500000+=+66500h
h+=+37.594
37.594+%2F+2+=+18.797 2 hr days of sales
What part of 2 hours is .797 ?
.797+%2A2+=+1.594hrs
594%2A60+=+35min
14 days would be 2 weeks so, the 18th day would be friday
The extra 1 hr 35 min carries it over to saturday
The hours of sales are 37 hrs and 35 min
The sales = 2.5 million on the saturday after the
2nd week of sales
Hope I got it right
