Answer:

$36.30

Step-by-step explanation:

The cost of a chemistry set = $27.50

It marked up 32% on cost.

Now we have to calculate 32% of 27.50

32% × 27.50

$\frac{32}{100}$ × 27.50

= 0.32 × 27.50

= 8.80

Therefore, the new price would be 27.50 + 8.80 = $36.30

After marked up 32% on cost the price would be $36.30

PART A:
The generic equation of the line is:
y-yo = m (x-xo)
First we look for the slope of the line:
m = (y2-y1) / (x2-x1)
m = ((5000) - (6000)) / (4-3)
m = -1000
Then, we substitute any point in the generic equation:
(xo, yo) = (4, 5000)
Substituting:
y-5000 = (- 1000) (x-4)
Rewriting:
y = -1000x + 4000 + 5000
y = -1000x + 9000
The equation is:
y = -1000x + 9000

PART B:
For the price of 3.50 we have:
y = -1000 * (3.5) +9000
y = 5500

Step-by-step explanation:

Step 1: Define

14x + 18 + x = -112(x + 36) + 13

Step 2: Solve for x

Distribute -112: 14x + 18 + x = -112x - 4032 + 13
Combine like terms: 15x + 18 = -112x - 4019
Add 112x on both sides; 127x + 18 = -4019
Isolate x term: 127x = -4037
Isolate x: x = -4037/127

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4-x and y = 2x + 3 intersect are the solutions of the equation 4-x = 2x + 3.

Because the point where the graphs intersect is a point that meets both rules (functions) y = 4 - x and y = 2x + 3 meaning that y from y = 4 - x equals y from 2x + 3 and also both x have the same value.

Part B: Make tables to find the solution to 4-x = 2x + 3. Take the integer values of x between -3 and 3.

x values 4 -x    2x + 3

-3 4-(-3)=7 2(-3)+3 =-3
-2 4-(-2)=6    2(-2)+3 =-1
-1 4-(-1)=5 2(-1)+3 = 1
0 4-0=4 2(0)+3 = 3
1 4-1=3    2(1)+3=5
2 4-2=2 2(2)+3 = 7
3    4-3=1    2(3)+3 = 9

The the solution is between x = 0 and x =1

Part C: How can you solve the equation 4-x = 2x + 3 graphically?

Draw in a same graph both functions y= 4 - x and y = 2x +3.

Then read the x-coordinates of the intersection point. That is the solution.
