<span># of books = 4 ; original cost = 4*9=36; savings = 0.10*36= 3.60
</span>
<span># of books = 2 ;original cost = 2*20=40; savings = 0.20*40= 8.00
</span>
<span>Percent savings:
original total cost=$76
Total savings = $11.60
Percent savings: 11.60/76 = 0.1526..= 15.26%</span>
The answer should be 432.
Answer:
s = 36
Step-by-step explanation:
So what you do is isolate the s.
1. Subtract 14 from both sides of equation. You should have:
1/3s = 12
2. To isolate the s, you multiply by 3 on both sides to get rid of the fraction on the left side. You should have:
s = 36
To verify, plug into original equation:
1/3*(36) + 14 = 26
1/3 * 36 = 36/3 = 12
12 +14 = 26
We can verify.
Answer:
w = .5
Step-by-step explanation:
-4w + 18w+2=10 -6w
14w + 2 -2 = 10 -2 -6w
14w + 2w = 8 - 2w + 2w
16w = 8
16w/16 = 8/16
w = .5
