You find 8% of 55.35 which is 4.42
Then you find 15% of 55.35 which is 8.30
You add them together which equals 12.72
You then subtract 12.75 from 55.35 55.35-12.75=42.63
The original price was $42.63
0 = -16t^2 -60t +54
t = 0.75 seconds

<h2>'
' in the form of 
- b.</h2>
Step-by-step explanation:
We have,
+ 8x + 15
To express + 8x + 15 in the form of - b = ?
∴ + 8x + 15
Adding and subtracting 1, we get
= + 8x + 15 + 1 - 1
= + 8x + 16 - 1
= + 2(x)(4) + 
- 1
Using the algebraic identity,
=
Thus, in the form of - b.
P = a + b + c
p = 2400
a = longest = 2c - 200
b = middle = a - 200 = 2c - 200 - 200 = 2c - 400
2400 = (2c - 200) + (2c - 400) + c
2400 = 5c - 600
2400 + 600 = 5c
3000 = 5c
3000/5 = c
600 = c <== shortest side
a = 2c - 200.....= 2(600) - 200 = 1200 - 200 = 1000<== longest side
b = 2c - 400...= 2(600) - 400 = 1200 - 400 = 800 <== middle side
So if she makes 8 and hour and works 40 hours a week
Thats 320 take home every week
Now divide that number by 8 as she is only taking home 1/8th and you are left with only 40 dollars saved a week.
Meaning to get to 457 it would take 11.425 weeks of work
