Answer:
5%.
Explanation:
220 is the starting value.
209 is the decreased value.
To calculate a percentage decrease, you must first subtract the starting value from the decreased value.
220 - 209 = 11.
Then, divide the difference by the absolute value of the starting value.
**ABSOLUTE VALUE - A NUMBER'S DISTANCE FROM 0.**
The absolute value of 220 is 220.
11 / 220 = 0.05.
Lastly, multiply the quotient by 100
0.05 × 100 = 5.
Therefore, the price was reduced by 5%.
The product is positive; this means there was a decrease in price, and not an increase. Ex. 5
If the product is negative, this means there was an increase in price, and not a decrease. Ex. -5
