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.

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

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

$(1.0225)^{40}P = 300$

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

$P = 123.19$

astraxan [27]

Answer:

12

Step-by-step explanation:

1st of all we should let the ration of boys to girls be 2x and 3x.

After that we should make the sum between 2x and3×and the sum of 2numbers is equal to 30

i.e.2x+3x=30

Then ,by solving this eqation we get the value of x=6

After that put the value of x in the number of boys

i.e.

2x=2×6=12

Hence ,the number of boys is 12

I need help ASAP <br> 120>10n+20

Burka [1]

Answer:n = 10 can make the inequality true

Step-by-step explanation:

The given inequality is

120 greater than or equal to 10n + 20. This means that the least value of n that would make the inequality true would be 10.

If we substitute n = 10 into the right hand side of the given inequality, it would result to 120.

So n = 10 can make the inequality true.
