As a result of the 53 week year in fiscal 2017, our 2018 fiscal year began one week later than our 2017 fiscal year. The comparable store revenue discussion presented below has been prepared by shifting forward our 2017 fiscal year results by one week, in order to provide more useful information to investors to better analyze our business. We have estimated that the one week shift would result in total revenues for the comparable 2017 period being $4,288 higher than the total revenues reported in thetwenty-six week period ended July 30, 2017. We have estimated that 2017 comparable store sales would be $2,951 higher and that 2017non-comparable stores and other sales would have been $1,337 higher.
The net increase in revenues for thetwenty-six weeks ended August 5, 2018 compared to the reportedtwenty-six week period ended July 30, 2017 were from the following sources:

The increase in cost of food and beverage as a percentage of revenue was driven by higher meat costs resulting from our upgraded burger product, higher commodity costs in our poultry and potato items as well as the impact of our largernon-comparable store group, partially offset by increases in food and beverage prices.
Cost of amusement and other increased to $42,677 in thetwenty-six week period ended August 5, 2018 compared to $34,261 in thetwenty-six week period ended July 30, 2017.

This increase was due primarily to a $2,531, or 80 basis point, amusement cost reduction in thetwenty-six week period ended July 30, 2017, for the favorable settlement of a multi-year use tax audit by the state of Texas. This cost reduction represents the excess use tax on redemption items during the period from July 2011 through January 2017.
