Final answer:
Without the specific costs of the clubs, games, and hot dogs, it is not possible to provide the correct total cost of Gloria's activities before tax. A coupon was used for 1/2 off the club rental, which would be included in the overall calculation.
Step-by-step explanation:
The question revolves around basic arithmetic operations to determine Gloria's total cost before tax for activities related to golfing. The specific costs for the clubs, games, and hot dogs are not given, so we cannot calculate the total cost. Additionally, Gloria used a coupon for 1/2 off her club rental, which would also affect the total. The key part of this question is understanding how to apply a discount and add costs to find a total before tax.
