Answer:
y = - x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (5, - 4) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = = = -
Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - x - 1 ← equation in slope- intercept form
To answer this item, I assume that it is compounded yearly such that the amount of interest (I) from the given present worth (P), interest rate (i) and the number of years (n) is calculated through the equation,
I = P x (1 + i)^n - P
Substituting,
I = ($55) x (1 + 0.04)^5 - $55
I = 11.91
The answer is nearest to the first choice, $11.
Answer:
710%
Step-by-step explanation:
Find each unit price.
16.20 $/bucket × (1 bucket / 450 eggs) = 0.036 $/egg
3.50 $/dozen × (1 dozen / 12 eggs) = 0.292 $/egg
The percent markup is:
(0.292 − 0.036) / 0.036 × 100% ≈ 710%
The store marks up the price by approximately 710%.
