Answer:
$14,277.80
Step-by-step explanation:
The standard formula for compound interest is given as;
A = P(1+r/n)^(nt) .....1
Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For this case;
P = $7,400
t = 8 years
n = 4 (quarterly)
r = 9.5% = 0.095
Using equation 1.
A = $7,400(1+0.095/4)^(4×7)
A = $7,400(1.02375)^(28)
A = $7,400(1.929432606035)
A = $14,277.80
final amount/value after 8 years A =$14,277.80
Product means the result you get after multiplying. So you have to multiply the two numbers. 379*8 = 3032
Given that,
Total number of children = 65
The ratio of boys to girls is 3 :2.
To find,
The number of girls in the grade.
Solution,
Let there are 3x girls and 2x boys.
ATQ,
3x + 2x = 65
5x = 65
x = 13
So, no of girls = 3x
= 3(13)
= 39
Hence, there are 39 girls in the grade.
