Answer:
$50.85
Step by step explanation:
We have been given that Jessica's Furniture Store buys a couch at a wholesale price of $113.00 and the markup rate at Jessica's Furniture Store is 45%.
We can find mark-up for the couch by finding 45% of 113.
Therefore, mark-up for the couch will be $50.85.
Answer:
- -35/3, -140/3, - 560/3, -2240/3
- 7, -28, 112, - 448
Step-by-step explanation:
<u>The terms are:</u>
<u>Given:</u>
- a₁ = a₂ + 35
- a₃ = a₄ + 560
<u>Use the nth term formula:</u>
- a₂ = a₁r
- a₃ = a₁r²
- a₄ = a₁r³
<u>Substitute:</u>
- a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35
- a₁r² = a₁r³ + 560 ⇒ a₁(1 - r)r² = 560
<u>Divide the second equation by the first:</u>
- r² = 560/35
- r² = 16
- r = √16
- r = ± 4
<u>Use the first equation to find the first term:</u>
- a₁( 1 ± 4) = 35
- 1. a₁ = 35/-3 = -35/3
- 2. a₁ = 35/5 = 7
<u>We have two sequences:</u>
r = 4
- -35/3, -140/3, - 560/3, -2240/3
r = -4
Answer:
y=-1/3x+5
Step-by-step explanation:
<u>Slope-intercept form</u>
y=mx+b
m => slope
b => y-intercept
<u>Slope</u>
m=(y2-y1)/(x2-x1)=(5-4)/(0-3)=1/(-3)=-1/3
<u>Y-intercept</u>
y=-1/3x+b
5=-1/3(0)+b
5=b
<u>Final equation</u>
y=-1/3x+5
