The sale price of the baseball bat is $14.00. Option B is correct.
To determine the initial discount, multiply the original price by (1 - 0.50), which is equivalent to multiplying by 0.50. This yields the first discounted price.
Original Price * 0.50 = $35.00 * 0.50 = $17.50
To the initial discounted price, apply the second 20% discount. The same as multiplying by 0.80, multiply by (1 - 0.20).
Sale Price = First Discounted Price * 0.80 = $17.50 * 0.80 = $14.00
Therefore, the sale price of the baseball bat is $14.00.
