Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5

Micah pays 54$ for an item originally priced 60$. What percentage of the original price was his discount?

pantera1 [17]

Answer: The percentage of the original price was his discount = 10%

Step-by-step explanation:

Given: original price = $60

Price after discount = $54

Discount = Price after discount - original price

= $ (60-54) = $6

The percentage of the original price was his discount = $\dfrac{Discount}{Original\ price}\times100$

$=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%$

Hence, the percentage of the original price was his discount = 10%
