Calculating the increase or decrease of a value in percentage
1) The original price of a Batman toy was $20. If the price is reduced by 20%, what is the new price of the Batman toy?
$19
$17
$16
$18
1/10
Solution
Answer:
$16
Explanation:
Cost of Batman toy = $20
Let the total % be 100%
If we reduce 20% we would get
= 100 - 20
= 80%
New price of the Batman toy = 20 × (80/100)
= $16
