What is an expression for the sale price of a bracelet that has been discounted 20% from its
sticker price? evaluate the expression for a sticker price of $40. use the variable for the sale
price and for the sticker price.
a. = - 0.2; $32
b. = + 20; $840
c. = + 0.2; $40
d. = - 0.8; $8

The answer is A.) -0.2; $32

The reasoning behind the answer is because the sale is 20% off of the original price which could be written as Original-20%. 20% written in decimal form is 0.2. Since the original price is $40 you can rewrite the expression to be $40-0.2(40). So the sale price is -0.2 and the sticker price is 32 since 20% of 40 is 8 and 40-8=32
