NARRATOR: Question five. David buys a skateboard at a discounted price of $85. If the skateboard was originally $120, what was the percentage discount? Round your answer to the nearest percentage. Method one. The discount is $120 minus $85, so $35. The percentage discount can be worked out by finding the discount out of the original price, multiplied by 100% to convert to a percentage. So we have $35 out of $120 multiplied by 100%. 35 out of 120 simplifies to 7 out of 24 multiplied by 100%, which gives us 700 out of 24%. Which works out as 29.16 recurring percent, so the percentage discount correct to the nearest percent is 29%. Method two. Find what percentage the new price is of the old price. So David paid $85 out of a possible $120, multiplied by 100% to convert to a percentage. 85 out of 120 is 17 out of 24.

[The fraction 17 on 24 is multiplied by 100%.]

NARRATOR: To give 1,700 out of 24%, which is 70.83 recurring percent, so approximately 71%. So $85 is approximately 71% of $120, which means that the price has been discounted by 100 minus 71, which is 29%.
