The price of a video game was reduced from $70.00 to $40.00. By what percentage was the price of the video game reduced? Justify your answer.
The priced changed from 70 to 40. So, the % change is
(40-70)/70 = -30/70 = -0.43 or -43%
The negative value means that the price decreased. We didn't really need that for this problem, since we already knew that the change was a decrease. In other exercises, though, it may not be obvious at first, and your answer will have to reflect whether the change was positive or negative.
Is that is or is there something else...I am so confuse
% change = (actual change) / (original price)
I try my best, but I have trouble understanding things and that's why I came to Jiskha, this is my first time
confused.
I divided 40/70 and got 0.57 or 57%. Idk
No. what was the actual change? from 70 to 40 is a change of 30
what was the original price? 70
to get correct answers, read things carefully.
To find the percentage by which the price of the video game was reduced, we need to calculate the difference between the original price and the reduced price, and then express that difference as a percentage of the original price.
First, we calculate the difference between the original price and the reduced price:
$70.00 - $40.00 = $30.00
Next, we express this difference as a percentage of the original price. We can do this by dividing the difference by the original price and then multiplying by 100:
($30.00 / $70.00) * 100 ≈ 42.86%
Therefore, the price of the video game was reduced by approximately 42.86%.
