<h3>What is the percentage?</h3>
The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that Mikaela purchased a paddleboard originally priced at $699. If all merchandise was on sale for 40% off and the state tax rate is 7.25%.
Here,
Original cost = $699
Discount = 40% = 0.40
State tax rate = 7.25% = 0.0725
Total amount = Original cost × (1 - Discount) × (1 + State tax)
Total amount = 699×(1 - 40%)×(1 + 7.25%)
Total amount = 699×(1 - 0.40)×(1 + 0.0725)
Total amount = 299.87
Thus, the total amount that Mikaela spent on the paddleboard is $299.87.
