Arte-miy333 [17]

Answer:

9.52% ( to 2 dec. places )

Step-by-step explanation:

Calculate the percentage increase using

Allison invested $70,000 in an account paying an interest rate of 6.2%
jeka94

Answer and Step-by-step explanation:

First, you need to make the function to represent the information given.

We start with 70,000 in the account, and have an interest rate of 6.2%.

We want to know how long it will take to get $223,200.

The equation for simple interest is:

A = P(1 + rt)

Where A is the total amount, P is the principle amount of money, r is the rate, and t is the time.

Now, we plug in the values and solve for t.

223,200 = 70,000(1+6.2t)

\frac{\frac{223,200}{70,000} -1}{6.2}  = t

t = 0.353

Multiply by 100 to get the years.

t = 35.3

So, it will take Allison 35.3 years to get 70,000 dollars to 223,200 dollar with an interest rate of 6.2%

196 is the square of 14
So both can easily come out of the radical.

√196s² = <u>14s</u>
