(2x - y = -2)2
5x - 2y = -7
4x - 2y = -4
Subtract both
x = -3
5(-3) - 2y = -7
-15 - 2y = -7
-2y = 8, y = -4
Solution: (-3,-4)

Mica bought a new smart phone for $258.13. That was the price after his 18.25% discount. What was the original price of the phon

julia-pushkina [17]

The original price of phone is $ 315.76

Solution:

Given that Mica bought a new smart phone for $ 258.13.

That was the price after his 18.25% discount

To find: original price of phone

From given question,

price after discount = $ 258.13

discount = 18.25 %

Let "x" be the original price of phone

price after discount = original price - discount

$258.13 = x - 18.25 \% \text{ of } x$

$258.13 = x - \frac{18.25}{100}x$

$258.13 = x(1 - \frac{18.25}{100})$

$258.13 = x(1 - 0.1825)\\\\258.13 = x( 0.8175)\\\\x = \frac{258.13}{0.8175}\\\\x = 315.76$

Thus original price of phone is $ 315.76
