Sn=A1(1-r^n)/(1-r)
Sum of a finite geometric series formula
We know the sum, number of terms and rate, so you plug those in.
-255=A1(1-(-4)^4))/(1-(-4)
-255=A1(1-256)/5
-255=A1(-255)/5
-1275=A1(-255)
5=A1
Hope this helped! Let me know if you have any questions.
Answer:
209.5 grams are protein
Step-by-step explanation:
Protein is 25 % or .25
We have 838 grams of peanut butter
25% of it is protein. Multiply the grams by the percent that is protein to determine how many grams are protein
grams protein = total grams times percent protein
=838*.25
= 209.5 g
At the end of the first full month the interest acquires is $ 1.30.
<u>Step-by-step explanation:</u>
Since we are looking for the interest for full month, we have to divide the APR by 12.
Because APR is the interest amount for the full year.
So 3.75 % = 3.75/100 = 0.0375
Now multiplying, we will get
415 × 0.0375/12 = $ 1.30
