Answer 1

The discount percent and the cost of a jacket are given as 5% and $76 respectively. To find the original cost of the jacket we woukd take the following steps;

$\begin{gathered} \frac{95}{100}=\frac{76}{x} \\ \frac{19}{20}=\frac{76}{x} \\ \text{Cross multiply and you have;} \\ 19x=1520 \\ \text{Divide both sides by }19 \\ x=80 \\ \text{Please note that the discount is 5\% of the original price, which means} \\ \text{The cost given as \ 76 is now 95\% of the original cost} \\ x\text{ in the equation now represents the original cost} \end{gathered}$

Therefore, the correct answer is option C which is $80
