The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%
b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
Answer:
20x + 22
Step-by-step explanation:
34- 4x + 12x -12 +12x
step 1: 34 - 12 = 22
now you have left: -4x + 12x +12x
step 2: 12x +12x = 24x
step 3: 24x - 4x = 20x
Now you will combine the two answers you got: 20x +22
Hope this helps :)
