A. You can get this through the process known as completing the square.
Answer:
The amount is $16718.7 and the interest is $4718.7.
Step-by-step explanation:
STEP 1: To find amount we use formula:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$12000 , r=3.33% , n=4 and t=10 years
After plugging the given information we have
AAAA=12000(1+0.03334)4⋅10=12000⋅1.00832540=12000⋅1.393225=16718.7
STEP 2: To find interest we use formula A=P+I, since A=16718.7 and P = 12000 we have:
A16718.7II=P+I=12000+I=16718.7−12000=4718.7
Answer:
Step-by-step explanation:
Let x be the original number.
x - 15 - 1/2(x - 15) - 10 = 12
x - 15 - 1/2 x + 7.5 - 10 = 12
1/2x - 25 + 7.5 = 12
1/2x - 17.5 = 12
1/2x = 27.5
x = 55
1. a. 35 = 3J - 1
b. n = A + 2
2. a. P = 250 + 10n
b. P = 250 + 10(20) = $450
