Jerry bought a DVD recorder for $280. Now it is on sale for $220. Find the percent of change in the price. Round to the nearest whole if necessary.

21% decrease

Step-by-step explanation:

Amount of change/original amount

280-220=60

60/280 = 21.428571 which rounds to 21%

Step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

there is no graph so i cant sorry
