Answer:
$38.80
Step-by-step explanation:
The full price of the pole may be written as 1.00($97), or $97.00.
The discount was 0.60($97), or $58.20. Subtracting this from the full price yields the sale price: $97.00 - $58.20 = $38.80.
1.04($38.80) results in the price Alfredo paid for the pole: $40.35. Note that the '1' corresponds to 'price before tax' and that the '.04' corresponds to the 4% tax.
