The student store sells pencils that have a markup of 120 percent above their wholesale cost of $0.50 each. they also charge sales tax of 8 percent. what is the total cost of a pencil from the student store?

The total cost of a pencil from the student store is $ 1.188

Step-by-step explanation:

Given,

The original cost or wholesale cost of each pencil = $ 0.50,

Markup percentage = 120 %,

So, the cost of the pencil after markup = 0.50 + 120% of 0.50

Now, sales tax = 8 %,

Hence, the final total cost of a pencil = 1.1 + 8 % of 1.1

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
