A farmer is comparing the number of eggs laid by two hens. The first hen laid 8 eggs per week for x weeks. The second hen laid 9
CaHeK987 [17]

Answer:

8x > 9y

Step-by-step explanation:

Since the first hen laid 8 eggs a week, the amount of eggs can be represented by 8x.

The second hen laid 9 eggs a week, so it can be represented by 9y.

The first hen laid more eggs than the second hen, so use a greater than inequality.

Nancy opened a savings account 7 years ago. The account earns 5% interest, compounded quarterly. If the current balance is $1,00
Troyanec [42]

The amount deposited initially is $ 706.22

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

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

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

Where,

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

From given,

t = 7 years

A = 1000

P = ?

r = 5 \% = \frac{5}{100} = 0.05

n = 4 (since compounded quarterly)

Substituting the values we get,

1000 = p(1+\frac{0.05}{4})^{4 \times 7}\\\\1000 = p(1+\frac{0.05}{4})^{28}\\\\1000 = p(1+0.0125)^{28}\\\\1000 = p(1.0125)^{28}\\\\1000 = p \times 1.4159923\\\\p = \frac{1000}{1.4159923}\\\\p = 706.2185 \approx 706.22

Thus amount deposited initially is $ 706.22
