Remark
The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?
Solution
36 * (x/100) = 29.52 Multiply both sides by 100
36 * x = 29.52 * 100 The 100 on the left disappears.
36 * x = 2952 The decimal disappears. Divide by 36
x = 2952/36
x = 82%
That is not your answer. That just tells you what % of 36 is that would give 29.52
Answer
The % discount is 100 - 82 = 18%. That is the % discount.
Answer:

Step-by-step explanation:
We have been given that a polynomial function
models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.
In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:

The zeroes of this polynomial occur when either
or
.
The equation
have no real solutions. Therefore, the only time when the roller coaster is at the ground is at 
Answer:
The sales tax is equal to 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Let
y-----> the cost of the purchase
x ----> the sales tax
step 1
Find the value of k
For 
substitute



The linear equation is equal to

step 2
what would be the sales tax on a purchase of $46
For 
substitute in the equation



Answer:
s = -15
Step-by-step explanation:
-12 + (-18) = -30
-30= 2s
-15 = s
