D

Step-by-step explanation:

Take the total amount needed and subtract the amount they have

190.44 -34.20

156.24

Divide by the number of weeks they are saving

156.24/8

19.53

They need to save more than this amount because they need to save more than 190.44.

There is an open circle at 19.53 and a line going to the right

When dante was born, his grandparents deposited $10,000 into a special college fund that paid 4% annual interest, compounded mon
RSB [31]

Using compound interest, it is found that Dante was 6.6 years old when the balance in the account reached $13,000.

<h3>What is compound interest?</h3>

The amount of money earned, in compound interest, after t years, is given by:

A(t) = P\left(1 + \frac{r}{n}\right)^{nt}

In which:

  • A(t) is the amount of money after t years.
  • P is the principal(the initial sum of money).
  • r is the interest rate(as a decimal value).
  • n is the number of times that interest is compounded per year.

In this problem, we have that the parameters are given as follows:

A(t) = 13000, A(0) = 10000, r = 0.04, n = 12.

Hence the time in years is found as follows:

A(t) = P\left(1 + \frac{r}{n}\right)^{nt}

13000 = 10000\left(1 + \frac{0.04}{12}\right)^{12t}

(1.0033)^{12t} = 1.3

\log{(1.0033)^{12t}} = \log{1.3}

12t\log{1.0033} =  \log{1.3}

t = \frac{\log{1.3}}{12\log{1.0033}}

t = 6.6
