Answer:
18. $4.50
19. $18
Explanation:
18.
The discount is 15%.
The original price is $30.
The discount is 15% of $30.
To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100.
15% of $30 = 15% × $30 = 0.15 × $30 = $4.50
19.
The discount is 25%.
The original price is $24.
The discount is 25% of $24.
To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100.
25% of $24 = 25% × $24 = 0.25 × $24 = $6
The discount is $6.
Now we subtract the amount of the discount, $6, from the original price.
$24 - $6 = $18
Answer: $18
