Clare made $160 babysitting last summer. She put the money in a savings account that pays 3% interest per year. If clare doesn't
AVprozaik [17]

We have been given that Clare made $160 babysitting last summer. She put the money in a savings account that pays 3% interest per year. If Clare doesn't touch the money in her account, she can find the amount she'll have the next year by multiplying her current amount 1.03.

We are asked to write an expression for the amount of money Clare would have after 30 years if she never withdraws money from her account.

We will use exponential growth function to solve our given problem.

An exponential growth function is in form y=a(1+r)^x, where

y = Final value,

a = Initial value,

r = Growth rate in decimal form,

x = Time.

3\%=\frac{3}{100}=0.03

We can see that initial value is $160. Upon substituting our given values in above formula, we will get:

y=160(1+0.03)^x

y=160(1.03)^x

To find amount of money in Clare's account after 30 years, we need to substitute x=30 in our equation.

y=160(1.03)^{30}

Therefore, the expression 160(1.03)^{30} represents the amount of money that Clare would have after 30 years.

25) Margie needs to borrow $9,000 from a local bank. The
azamat

Answer:

B) $3060.00

Step-by-step explanation:

8.5% of 9,000 equals 765, then 765 multiplied by 4 equals 3060.

I think that it will take Margie 4 years to pay back the bank. And the interest rate that the bank charges is 8.5% per month.

I'm not sure if this is correct

What is the slope of the line?
White raven [17]

Answer:

-\frac{2}{3} x

Step-by-step explanation:

Hey there!

To find slope, you take \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case

y2: 6

y1: 4

x2: -3

x1: 0

Now we plug in this information

\frac{6-4}{-3-0} \\\\\frac{2}{-3} \\\\-\frac{2}{3}

Since this is the slope, you have to add a "x"

So, the slope is -\frac{2}{3} x
