Respuesta :

120 pound is the full price.

Answer:

120 pounds

Step-by-step explanation:

The cost of refurbished phone after 35% off = 78.00 pounds

Let the cost of phone before the discount be x

x - (35% of x) = 78

x -  [tex]\frac{35}{100}x[/tex] = 78

x - 0.35x = 78

0.65x = 78

x =  [tex]\frac{78}{0.65}[/tex]

x = 120

The cost of phone before the discount would be 120 pounds.
