Answer:
Explanation:
You can convert the percent markup into a multiplicative factor in this way:
Base price: 15,800 . . . (cost to the seller)
Percent mark up: 115% . . . (based on the cost to the seller)
Sale price: 15,800 + 115% of x = 15,800 + 115 × 15,800 /100 =
= 15,800 + 1.15 × 15,800 = 15,800 (2.15) = 33,970
The markup is:
- Markup = price paid by the seller - cost to the seller = 33,970 - 15,800 = 18,170 (notice that this is 115% of 15,800)
And <em>the percent markup based on the sale price is</em>:
- % = (markup / sale price) × 100 = (18,700 / 33,970) × 100 =
= 53.49 %
Rounding to the nearest tenth percent that is 53.5 %.
I think it would be the answer a or b
Answer:
40 terms
Step-by-step explanation:
the sum to n terms of an arithmetic sequence is
= 
(a₁ + 
)
then
(- 4 - 82) = - 1720 ( multiply both sides by 2 to clear the fraction )
- 86n = - 3440 ( divide both sides by - 86 )
n = 40
the series has 40 terms
