Question

Headphones that originally cost $80 were marked up to $92. By what percentage were the headphones marked up?

Answer 1

Given:

Headphones that originally cost $80 were marked up to $92

To find:

By what percentage were the headphones marked up?

Solution:

The original cost price of the headphones = $ 80

The marked-up price of the headphones = $ 92

Now,

The percentage by which the headphones were marked up was,

= $\frac{Marked-up\:Price \:- \:Original \:Price}{Original\:Price} \times 100$

substituting the given values of marked-up price and original price, we get

= $\frac{92 \:-\:80}{80}\times 100$

= $\frac{12}{80}\times 100$

= $\frac{3}{2}\times 10$

= $3 \times 5$

= $\bold{15\%}$

Thus, the headphones were marked up to → 15%.
