7th Grade Tax Tip and Discount Word Problems Solutions

Start by calculating the sales tax or discount based on the percentage given. Multiply the original price by the tax or discount rate to find the amount to be added or subtracted.

For tax calculations, use the formula: original price × tax rate. This gives you the tax amount, which should be added to the original price to find the total cost. Double-check that you’re applying the correct percentage, as it can be easily mixed up with the decimal form.

For discounts, subtract the calculated discount from the original price. Make sure to first convert the percentage to a decimal (for example, 20% becomes 0.20) before applying it to the price. Recheck the final price to confirm accuracy.

Always verify your calculations by comparing your final result to example solutions. This ensures you’re on the right track and helps to solidify the process in your mind.
