Answer:
D. A(n) = P + (n-1)i*P
Step-by-step explanation:
The formula to calculate the simple interest is:
Replace i by 
, then
SI = Pni
where n is the number of years.
So, for n-1 years, the simple interest is:
SI = P(n-1)*i
The Total amount is:
A(n) = P + (n-1)i*P
Answer:
Option B. 16-8
Step-by-step explanation:
Let
z ------> the number of apple left
x -----> the total number of apples
y -----> the number of apples sold
we know that
The numerical expression of the phrase " the number of apples left if eight out of the sixteen apples have been sold" is equal to subtract the number of apples sold from the total number of apples
so
z=x-y
we have
x=16 apples
y=8 apples
substitute
z=16-8
17.90/22.95 = x/100
22.95x=1790
1790÷22.95= 77.99
x= 78% (estimated)
Answer: The sweater is 78% off
The answer I got was 360*10=6300
<span>The answer is B)11 rows. If there are an equal amount of woodwind and brass musicians in each row then there would be 7 woodwinds in every single row and 8 brass musicians in every row equaling 15 musicians for 11 rows making every row the exact same as the one before.</span>
