Answer to a math question 35% was taken off a phone because it was refurbished. The Now only price is £78. How much was the phone before the discounted price?
Let p represent the original price of the phone.
\left(1-\frac{35\%}{100\%}\right)\times p=78, 0.65p=78, p=\frac{78}{0.65}, p=120
So, the original price of the phone was £120.
