Answer:
The Cost Price will be $19.99
Step-by-step explanation:
James
Sale Price = (100 - Discount Rate) x Cost Price
Let Y = Cost Price
By Putting the values in above equation:
$16.99 = (100 - 15) x Y
$16.99 = 0.85Y
Dividing the equation by 0.85, we get
Y = $16.99 / 0.85
Y = $19.99
If you graph the two equations then you will find that they intersect at (-2,-2).
You then have to check your answer.
x=4y+6
(-2)=4(-2)+6
-2=-8+6
-2=-2
x-3y=4
(-2)-3(-2)=4
-2+6=4
4=4
