Step-by-step explanation:

You might be interested in
Reagan has a savings account that earns 1.87% interest, compounded quarterly. If she needs $20,857 for a down payment on a house
MatroZZZ [7]
To solve this, we are going to use the compounded interest formula: A=P(1+ \frac{r}{n} )^{nt}
where 
A is the final amount after t years
P is the initial investment 
r is the interest rate in decimal form 
n is the number of times the interest is compounded per year
t is the time in years

We know from our problems that she needs $20,857 for a down payment on a house in 9 years, so A=20857 and t=9. To convert the interest rate to decimal form, we are going to divide the rate by 100%
r= \frac{1.87}{100} =0.0187
Since the interest is compounded quarterly, it is compounded 4 times per year; therefore, n=4. 
Lets replace the values in our formula to find P:
A=P(1+ \frac{r}{n} )^{nt}
20857=P(1+ \frac{0.0187}{4} )^{(4)(9)}
P= \frac{20857}{(1+ \frac{0.0187}{4} )^{(4)(9)}}
P= \frac{20857}{(1+ \frac{0.0187}{4} )^{36}}
P=17633.17

We can conclude that the correct answer is: <span>B. 17,633.17</span>

Please help me with this​
ArbitrLikvidat [17]

Answer:

C and D are correct in my calculations, I'm confused.. ;w;

Step-by-step explanation:

4x + 9 + 79 - x + y = 180

4x - x + y + 79 + 9 = 180

3x + y + 88 = 180

3x + y = 180 - 88

3x + y = 92

y = 92 - 3x

A.) x = 64, y = 50

y = 92 - 3x

(50) = 92 - 3(64)

50 = 92 - 192

50 ≠ - 100

B.) x = 14, y = 152

y = 92 - 3x

(152) = 92 - 3(14)

152 = 92 - 42

152 ≠ 50

C.) x = 23.3, y = 22.1

y = 92 - 3x

(22.1) = 92 - 3(23.3)

22.1 = 92 - 69.9

22.1 = 22.1

D.) x = 14, y = 50

y = 92 - 3x

(50) = 92 - 3(14)

50 = 92 - 42

50 = 50
