$10,000 at 7% continuous compounding for 8 years

Answer: A
Answer:
600 ÷ 4 = 150
450 ÷ 3 = 150
The same thing either way.
They are considered proportional ratios
So what we do first is find out the cost per foot which is 305÷154=1.9805194805194805195
Then we find out the area of the second rug which is 288 feet and multiply that by the cost 1.9805194805194805195. We then get 1.9805194805194805195x288=570.38961038961038961
3 x^{2} - 15x - 42
(x-7)(x+2)
x-7=0 x+2=0
x=7,-2
