for this case you can solve the problem by a simple rule of three:   72→100%   x→30%   Clearing x we have:   x=(30100)⋅(72)=21.6$   Then, we must subtract this value from the original price:   72−21.6=50.4$  Answer:   Gabriela pays $ 50.4 with the discount

Since the glasses are 30% off, Garbriela will pay 100%−30% of the original price, or 70%. Therefore, Gabriela will pay $72⋅0.7=$50.40. The value of the discount may be calculated instead. Moving the decimal one place to the left would quickly yield the value of a 10% discount, $7.20. A 30% discount is three times that, or $21.60. Then we subtract this value from the original price of $72. $72.00−$21.60=$50.40 The final price Gabriela pays is $50.40.
