4. Four friends went on a trip to Mexico. They rented a car for eight days which cost

nlexa [21]

Explanation:

So, I know a lot of people won't do it this way, but this is how I would do it.

First, multiply each expense by eight (eight for the eight days)

$55 x 8 = 440

$25 x 8 = 200

$129 x 8 = 1032

Next, take the three answers and add them together:

440 + 200 + 1032 = 1672

Lastly, divide 1672 by four (four for the four friends)

1672/4 = 418

There you go! Here is your answer. Each friend paid $418

Hope I helped! :D

How much would $500 invested at 6% interest compounded monthly be worth after 4 years? Round your answer to the nearest cent

Rama09 [41]

1) Compound interest formula:
$A = P(1+ \frac{r}{n}) ^{nt}$ **
**A = amount, P = principal amount, r = rate, n = # of times interest is compunded every year, t = time(in years)
2) Plug numbers in
 $A = (500)(1+ \frac{0.06}{12}) ^{(12)(4)}$
3) Solve
A = 635.24458054

Hope this helped! Good Luck!
