A customer pays $18 for a DVD that originally costs $20. What is the percent decrease in the cost of the DVD?

1 answer:

5 0

Answer:

= 10 percent decrease

Step-by-step explanation:

Percent decrease = (original - new)/original * 100 percent

The original price was 20 and the new price is 18

= (20-18)/20 * 100 percent

=2/20 * 100 percent

= 1/10 * 100 percent

= 10 percent decrease

$8 = 4 - 2x\\8 + 2x = 4\\2x = -4\\x = -2$

$- 2x +5 = 17\\-2x =12\\x = -6$

$12= - 3 ( x+ 5)\\12 = -3x -15\\-3x =27\\x= -9$
