How do you put decimals into an average

answer:

see the attached formula (the "n" means number of years):

we know principal = $600,000 rate = .055 and "n" = 20

annual payout = principal * rate * (1 +r)^n / [(1 + rate)^n   -1]

annual payout = 600,000 * .055 * (1.055)^20 / [{(1.055)^20}-1]

annual payout = 600,000 * .055 * 2.9177574906 / 1.9177574906

annual payout = 96,286.00 / 1.9177574906

annual payout = 50,207.60

to get a monthly payout we divide by 12 and get:

4,183.97 per month

step-by-step explanation:

the quadratic formula is , where a, b, and c are values in the quadratic ax^2 + bx + c. plug in the values to get

amount of money that caitlin in her account = $ 402

in each week , she withdrew $ 15.

let number of weeks she had paid money for swimming lesson = $ 237

writing the above statement in equation form

⇒ 402 - 15 n = 237

⇒ 402 - 237 = 15 n

⇒ 15 n = 165

dividing both side by 15, we get

n= 11

→number of weeks that caitlin had learnt swimming = 11 weeks
