Answer:
Step-by-step explanation:
Equation of line is y = mx + b
m is the slope = -2
b is the y intercept = -1
:- y = -2x - 1
Look at the picture.
Corresponding angles:
∠1 and ∠5
∠2 and ∠6
∠3 and ∠7
∠4 and ∠8
<h3>Therefore your answer is ∠1 and ∠5</h3>
Markup = $4
b) markup as a percentage of cost is 33.3%
Step-by-step explanation:
Markup
markup = selling price - cost
= $13 - 9
... markup = $3
Markup as a Percentage of Cost
To find the percent markup, divide the markup by the reference value and multiply the ratio by 100%. The reference value for markup is usually cost price, but sometimes may be selling price.
... markup / cost × 100% = 3/9×100% = 33 1/3% ≈ 33.3%
