<h3><u>The original price of laptop before the discount is $ 1349</u></h3>
<em><u>Solution:</u></em>
Given that,
Sales price of laptop = $ 944.30
It is on sale for 30% off
To find: Original price of laptop before the discount
Let "x" be the original price of laptop before the discount
From given,
original price = sales price + 30 % of original price
x = 944.30 + 30 % of x
![x = 944.30 + \frac{30}{100} \times x\\\\x = 944.30 + 0.3x\\\\x - 0.3x = 944.30\\\\0.7x = 944.30\\\\Divide\ both\ sides\ by\ 0.7\\\\x = 1349](https://tex.z-dn.net/?f=x%20%3D%20944.30%20%2B%20%5Cfrac%7B30%7D%7B100%7D%20%5Ctimes%20x%5C%5C%5C%5Cx%20%3D%20944.30%20%2B%200.3x%5C%5C%5C%5Cx%20-%200.3x%20%3D%20944.30%5C%5C%5C%5C0.7x%20%3D%20944.30%5C%5C%5C%5CDivide%5C%20both%5C%20sides%5C%20by%5C%200.7%5C%5C%5C%5Cx%20%3D%201349)
Thus the original price of laptop before the discount is $ 1349
Answer:
ninety-eight dollars and three cents
Step-by-step explanation:
Answer:
f = 4 e = -2
Step-by-step explanation:
e - 2f = -10
8e + 4f = 0
Solve by substitution
8e + 4f = 0
8e = -4f
e = -0.5f
Substitute into e - 2f = -10
-0.5f - 2f = -10
-2.5f = -10
2.5f = 10
f = 4
Substitute into 8e + 4f = 0
8e + 16 = 0
8e = -16
e = -2
