Final answer:
The sale price of the bicycle is $225.
Step-by-step explanation:
To find the sale price of the bicycle, you need to calculate the discount amount. The discount is (1/4) off the regular price, which means you subtract 1/4 of the regular price from the regular price. The regular price is $300, so (1/4) of $300 is $75. Subtracting $75 from $300 gives you a sale price of $225.
