Answer:
$650. This was the original price.
Step-by-step explanation:
Let p represent the original price.
The following expression calculates the value of p: (1 - 0.38)p = $403. Note that '1' indicates full price and that '0.38' indicates a 38% discount.
(1 - 0.38)p = $403 simplifies to (0.62)p; = $403.
Dividing both sides by 0.62 yields $650. This was the original price.
$650
Line up $ with $ and % with % then cross multiply
$403 represents ........100% full price -38% discounted = 62%
$ x amount of the original price represents .........................100%
x*62 = 403*100, cross multiply
x = (403*100)/62, divide both sides by 62
x = $650
Tell me if i am wrong. :)
To solve for y:
Q.1 2x + y = -1
y = -1 - 2x
Q. 2. 4x - 5y = 7
y = 7 - 4x over -5
