Step-by-step explanation:
13x - 21x - 7 = 63
- 8x = 70
x = - 8.75
X + y = 33
x - y = 9 Add the 2 equations together
---------------
2x = 42 Divide both sides by 2
x = 21
Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12
One list had 21 items on it and the other list had 12 items on it.
$14.8 was the markup, And the price went up in 22%, how I got my answer!
I first found that adding $64+$14.8=$78.8, and for percentage, that took awhile. At first I thought that it would be 20% but upon further investigation I found that, 22% Of $64 is $14.8.
I hope this helps!
P.S. 20% of $64 is $12.8.
