Step-by-step explanation:

We are going to make Sarah the variable "s."

Using the given information, the following equation is derived to calculate Sarah's distance.

S=2n-5

And the following equation will be used to calculate what Sarah collected using "p" for pledged money.

P=18S

If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.

P=18S
450=18S
450/18=S
25 miles = S

Using Sarah's distance, we can calculate Semir's either the first equation.

S=2n-5
25=2n-5
30=2n
15=n
Semir walked 15 miles.

We already found Sarah's distance to be 25 miles.

Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.

450-72=$378

His formula is the same as Sarah's, but we'll use SS for his variable.

P=18SS
378 = 18SS
378/18=SS
21= SS
SungSo walked 21 miles.

Greg deposited $4000 into an account with 4.6% interest, compounded semiannually. Assuming that no withdrawals are made, how muc

Zinaida [17]

The amount in account after 7 years is $ 5499.445

<em><u>Solution:</u></em>

<em><u>The formula for total amount in compound interest is given as:</u></em>

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

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

Here given that,

A = ?

P = 4000

t = 7 years

$r = 4.6 \% = \frac{4.6}{100} = 0.046$

n = 2 ( since compounded semi annually)

<em><u>Substituting the values in formula, we get</u></em>

$A = 4000(1+\frac{0.046}{2})^{2 \times 7}\\\\Simplify\ the\ above\ expression\\\\A = 4000(1+0.023)^{14}\\\\A = 4000(1.023)^{14}\\\\A = 4000 \times 1.37486\\\\A = 5499.445$

Thus amount in account after 7 years is $ 5499.445
