5%

Step-by-step explanation:

220/11 = 20

100% / 20% = 5%

hope this helps you 😉

5%.

Step-by-step 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
