Question

A video game is on sale for $41.30 after being on sale for 30% off. What was the original cost? A $66.30 B $71.30 C $62 D$59

Answer 1

A video game is on sale for $41.30

Selling price = $41.30

The video game is on sale for 30%

as the video game is at $41.30

i.e Intial selling price - 30% of Initials selling price 41.30

Let the initial selling price is x

Intial selling price - 30% of Initials selling price 41.30

x - 30% of x = 41.30

`\begin{gathered} x\text{ - 30\% of x = 41.30} \\ x-(30* x)/(100)=41.30 \\ x-(3)/(10)x=41.30 \\ x(1-(3)/(10))=41.30 \\ x((10-3)/(10))=41.30 \\ x*(7)/(10)=41.30 \\ x=41.30*(10)/(7) \\ x=59 \end{gathered}`

x = 59

As x represent the initial cost of the game

SO, The initial cost of the game is $59

Answer : d) 59
