Answer:

log\boxed{7}

Step-by-step explanation:

  • log\frac{14}{3}+log\frac{11}{5}-log\frac{22}{15}

  • =log\bigg(\frac{14}{3}*\frac{11}{5}\bigg)-log\frac{22}{15}

  • =log\bigg(\frac{14*11}{3*5}\bigg)-log\frac{22}{15}

  • =log\bigg(\frac{154}{15}\bigg)-log\frac{22}{15}

  • =log\bigg(\frac{154}{15}\div\frac{22}{15}\bigg)

  • =log\bigg(\frac{154}{15}\times\frac{15}{22}\bigg)

  • =log\bigg(\frac{154}{22}\bigg)

  • =log\boxed{7}

Maureen earned some money doing odd jobs last summer and put it in a savings account that earns 9% interest compounded quarterly
ivolga24 [154]

Answer:

Maureen earned $123.19 doing odd jobs

Step-by-step explanation:

The compound interest formula is given by:

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

Where 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 unit year and t is the time in years for which the money is invested or borrowed.

In this question:

Compounded quarterly means that n = 4

10 years, so t = 10

9% interest, so r = 0.09

There is $300.00 in the account, which means that A = 300

How much did Maureen earn doing odd jobs?

This is P.

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

300 = P(1 + \frac{0.09}{4})^{4*10}

(1.0225)^{40}P = 300

P = \frac{300}{(1.0225)^{40}}

P = 123.19

Maureen earned $123.19 doing odd jobs
