Using the compound interest formula,
572.86=287,50(1+i)^8
(1+i)^8=572.86/287.50=1.992557
1+i=(1.992557)^(1/8)=1.0899996
=>
i=1.0899996-1=9%
Note: This problem can also be solved in the head using the rule of 72.
Since after 8 years, the amount is roughly doubled, we can say that the interest rate is approximately 72/8=9%
Answer:
Slope intercept form: y= -x-2
Slope: -1
Y-intercept: -2

Answer:
1) N5.00
2) N1.50
Step-by-step explanation:
1) 1/2+1/4+1/5=10/20+5/20+4/20=19/20=95%
That means the 4th girl received 5%.
25 is 5% of 500
500 Kobo is N5.00
2) He lost 55%, so they means he has 45% left.
67.5 is 45% of 150
(67.5/0.45=150)
150Kobo is N1.50
The function represents a linear relation so I assume the answer is B neither
Answer:
a = 19
Step-by-step explanation:
a=2b-c
a= 2(11) - 3
a = 22 - 3
a = 19
