Step-by-step explanation:
i think a is 50,000? if you go along the x axis until you get to 40 and then go up and see where the blue line is the blue line is on 50,000
The formula is
A=p (1+r/k)^kt
A fund needed 30000
p Amount invested?
R interest rate 0.1
K compounded semiannual 2
T time 1 year
Solve the formula for p to get
P=A÷(1+r/k)^kt
P=30,000÷(1+0.1÷2)^(2×1)
P=27,210.88
Answer:
2 times. (2.0727272727)
Step-by-step explanation:
Proportion: 
Cross-multiply. 1 x 57 = 57. 27.5 x X = 27.5X
Get X by itself. 57 / 27.5 = x = 2.072727...
About two times.
Divide by 10000 to go to kilometer from centimeter
and km is not a weight unit
$64x20%=$12.80
$64-$12.80=$51.20
