Hello there,
Actual price = $100
After 10% discount = $100 - (10/100 x 100)
= $90
After 15% discount = $90 - (15/100 x 90)
= $76.50
Final cost - $76.50
Hope this helps :))

Answer:
the answer is 7 units
Step-by-step explanation:
We want to multiply the monomial 
by the monomial 
.
Remember that to multiply monomials we need to use the laws of exponents; in this case, the law for multiplying powers with the same base. The rule says that, when you multiply powers of the same base, you just need to add the exponents: 
, 
. Also, is worth pointing out that the exponent of a variable with no exponent is 1: 
.
Remember that we also need to multiply their coefficients , which are the numbers that multiply the variables; again, variables with no numbers have a coefficient of 1, so 
. Multiply coefficients is easy, you just need to multiply them as you usually do with everyday numbers.
Let's apply all of that to our multiplication:
We can conclude that 2x times x squared is 2x cubed.
S = 5 + C
33 = S + C

The rate of change is 2.
The rate of change is constant.
======================================================
Explanation:
The first point on the left is when x = 1.5 and it has a height of y = 1
The point (1.5, 1) is on the line.
So is the point (3,4) for similar reasoning.
Compute the slope between those points
m = (y2-y1)/(x2-x1)
m = (4-1)/(3-1.5)
m = 3/(1.5)
m = 2
The slope is 2, which is the same as saying the rate of change is 2. This only applies when x > 1 of which the interval 1.5 ≤ x ≤ 3 is a part of.
Since the slope stays at 2 on the interval 1.5 ≤ x ≤ 3, this means we consider the slope to be constant. If the curve bended at all on this interval, then it wouldn't be a constant slope.
