Explanation

The correct answer is $4.06$ . It's given that the retail price is $290 percent sign$ of the wholesale price of $dollar sign 7.00$ . Thus, the retail price is $dollar sign 7.00 left parenthesis StartFraction 290 Over 100 EndFraction right parenthesis$ , which is equivalent to $dollar sign 7.00 left parenthesis 2.9 right parenthesis$ , or $dollar sign 20.30$ . It's also given that the discounted price is $80 percent sign$ off the retail price. Thus, the discounted price is $$ 20.30 (1 - \frac{80}{100})$ , which is equivalent to $dollar sign 20.30 left parenthesis 0.20 right parenthesis$ , or $dollar sign 4.06$ .
