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: \(\color< blue >< percent = Part ÷ base >\). \(=340 \ ÷ \ 400=0.85=85\%\)
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: \(\color< blue > \ × \ whole >\).
\(part =\frac \ × \ 60 →\) \(part=\frac→\) \(part=\frac→\) \(part\) \(=9 \)

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