Question

a jacket at Rick's clothing store originally costs $27 the store is having a 45% off sale on all of its merchandise what is the sale price of the jacket

Answer 1

Let:

Op = Original price

Sp = Sale price

r = Discount

Express the discount percentage as a decimal:

45% = 45/100 = 0.45

The sale price will be given by:

`\begin{gathered} Sp=Op-0.45Op \\ where \\ Op=27 \\ so\colon \\ Sp=27-12.5 \\ Sp=14.85 \end{gathered}`

$14.85
