Step by step guide to solve Discount, Tax, and Tip problems

  • Discount \(=\) Multiply the regular price by the rate of discount
  • Selling price \(=\) original price \(–\) discount
  • Tax: To find tax, multiply the tax rate to the taxable amount (income, property value, etc.)
  • Tip: To find tip, multiply the rate to the selling price.

Discount, Tax and Tip – Example 1:

With a \(20\%\) discount, Ella was able to save \($40\) on a dress. What was the original price of the dress?

Solution:

\(20\%\) of \(x= 40, \frac{20}{100} \ × \ x=40, x=\frac{100 \ × \ 40}{ 20}=200 \)

The original price of the dress was \($200\).

Discount, Tax and Tip – Example 2:

Sophia purchased a sofa for \($340.00\). The sofa is regularly priced at \($400.00\). What was the percent discount Sophia received on the sofa?

Solution:

Use this formula: \(percent = Part ÷ base\) \(=340 \ ÷ \ 400=0.85=85\%\)
Therefore, the discount is: \(100\% \ – \ 85\%=15\%\)

Discount, Tax and Tip – Example 3:

Ella and her friends went out to eat at a restaurant. If their bill was \($60.00\) and they gave their server a \(15\%\) tip, how much did they pay altogether?

Solution:

The tip was \(15\%\). To solve \(15\%\) of \(60\) use this formula: \(\color{ blue }{part =\frac{percent}{100} \ × \ whole }\).
part \(=\frac{15}{100} \ × \ 60 →\) part \(=\frac{15 \ × \ 60}{100}→\) part \(=\frac{90}{10}→\) part \(=9 \)

The final amount they paid: \($60.00\) \(+\) \($9.00\) = \($69.00\)

Discount, Tax and Tip – Example 4:

The selling price of a table is \($400\) and the tax rate is \(6\%\) . What is the final price of the table?

Solution:

Find tax amount: \(6\%\) of \(400\)

To solve \(6\%\) of \(400\) use this formula: \(\color{ blue }{part =\frac{percent}{100} \ × \ whole }\).
part \(=\frac{6}{100} \ × \ 400 →\) part \(=\frac{6 \ × \ 400}{100}→\) part \(=\frac{240}{10}→\) part \(=24 \)

The final price of the table is: \($400\) \(+\) \($24\) = \($424\)
