Answer: To find Reid's final total, we need to calculate the discounted price for each item, add them up, and then add the sales tax.
For the helmet:
Discounted price = $85 - 0.3($85) = $59.50
For the protective gear:
Discounted price = $215 - 0.3($215) = $150.50
For the skates:
Discounted price = $113 - 0.3($113) = $79.10
For the stick:
Discounted price = $96 - 0.3($96) = $67.20
Now we can add up the discounted prices:
Total discounted price = $59.50 + $150.50 + $79.10 + $67.20 = $356.30
To find the sales tax, we need to multiply the total discounted price by 0.07:
Sales tax = 0.07($356.30) = $24.94
Finally, we can find Reid's final total by adding the total discounted price and the sales tax:
Final total = $356.30 + $24.94 = $381.24
Therefore, Reid's final total, factoring in the discount and sales tax, would be $381.24.
