875
Step-by-step explanation:
Answer:
$10.64
Step-by-step explanation:
We know that 1 pound, costs $4.25, so to begin I added that together. And gave myself 8.50. Now, we know that we have 2 pounds. We need 2.5 so, I devided 425 by 2, and got 213.5. Now I know I have to round to the nearest cent. And 213.5 would round to 214. Now we put the decimal back in place and add our 2.14 to our 8.50 and get $10.64
an = a1r^(n-1)
a5 = a1 r^(5-1)
-6 =a1 r^4
a2 = a1 r^(2-1)
-48 = a1 r
divide
-6 =a1 r^4
---------------- yields 1/8 = r^3 take the cube root or each side
-48 = a1 r 1/2 = r
an = a1r^(n-1)
an = a1 (1/2)^ (n-1)
-48 = a1 (1/2) ^1
divide by 1/2
-96 = a1
an = -96 (1/2)^ (n-1)
the sum
Sn = a1[(r^n - 1/(r - 1)]
S18 = -96 [( (1/2) ^17 -1/ (1/2 -1)]
=-96 [ (1/2) ^ 17 -1 /-1/2]
= 192 * [-131071/131072]
approximately -192
