Final answer:
To find the total amount Ray will spend, add the prices of the basketball and duffle bag and calculate the sales tax.
Step-by-step explanation:
First, find the total cost of the basketball and the duffle bag by adding their prices: $49.99 + $28.99 = $78.98
Next, calculate the amount of sales tax by converting the percentage to a decimal and multiplying it by the total cost: 0.06 × $78.98 = $4.74
Finally, find the total amount spent by adding the total cost and the sales tax: $78.98 + $4.74 = $83.72
