Since the price of the video game is $50
Since the discount from the point is 10%
Then multiply 50 by 10% to find the amount of the discount, then subtract it from $50

Subtract $5 from $50 to find the price after the discount for the points

Since there is another discount of $10, then
Subtract $10 from $45 to find the price at last

Sean pays $35 for the video game
