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
Answer:
8
Step-by-step explanation:

× 8
= 3
In algebra:
× y = 3
y = 3 ÷ 
y = 8

A=10, B=11, C=12, etc.


Now, the "only" thing that remains to do is solving the above equation.
While making this problem I only made sure it has a solution. I didn't try to solve it myself and I didn't know it will end up with such "convoluted" polynomial. Sorry to everyone who tried to solve it... m(_ _)m
I think the best way to approach it is using the rational root theorem since we know that
. Moreover we can deduce that
since there is
and
.
After you succesfully solve it, you should get the answer
.
The answer is 19.5
You add all the numbers to get 273 and divide by the amount of dots which is 14 to get 19.5
