Final answer:
To find the sale price of a boat marked up by 20% from an original price of $50, multiply the original price by 0.20 to find the increase ($10), then add it to the original price to get the sale price of $60.
Step-by-step explanation:
The student has asked to calculate the sale price of a boat that is marked up by 20% from its original price of $50. To find the sale price before sales tax, we follow these steps:
- Convert the percentage increase to a decimal: 20% becomes 0.20.
- Multiply the original price by the decimal rate of increase: $50 × 0.20 = $10.
- Add the increase to the original price to find the sale price: $50 + $10 = $60.
Therefore, the sale price of the boat, before any sales tax is applied, is $60.
