Grady marks down some $2.49 pens to $1.99 for a week and then marks them back up to $2.49. Find the percent of increase and the percent of decrease to the nearest tenth. Are the percents of change the same for both price changes? If not, which is a greater change

Answers

Answer 1

Answer: $2.49 -------------------100 %
$1.99 ------------------- x %
-------------------------------------
2.49 : 1.99 = 100 : x
x = ( 1.99 * 100 ) / 2.49 = 79.9 %
100 % - 79.9 % = 21.1 % ( Decrease )
$1.99 -------------------- 100 %
$2.49 -------------------- x %
------------------------------------
1.99 : 2.49 = 100 : x
x = ( 2.49 * 100 ) / 1.99 = 125.1 %
125.1 % - 100 % = 25.1 % ( Increase )
The percents of change are not the same.
The greater change is during the increase of price ( 25.1 % > 21.1 % ).

M+-2/3=-1/3 what is m?

Answers

$m + - (2)/(3) = - (1)/(3) \n \n m - (2)/(3) = - (1)/(3) \ / \ simplify \n \n m = - (1)/(3) + (2)/(3) \ / \ add \ (2)/(3) \ to \ each \ side \n \n m = (1)/(3) \ / \ simplify \n \n Answer: \fbox {m = 1/3} \ or \ \fbox {m = 0.3333}$

M+ -2/3= -1/3
⇒ M+ (-2/3)= -1/3
⇒ M= -1/3+ 2/3
⇒ M= 1/3

Final answer: M= 1/3~

Kim bought a poster that cost $8.95 and a ome colored pencils.The total cost was $21.35.How much did the colored pencils cost?

Answers

if the total cost was 21.35, and the poster cost 8.95, then all you need to do is subtract to poster cost from the total cost to find the cost of the pencil.
21.35-8.95= $12.40

$21.35 - $8.95 = your answer: 12.4
