A) 0.15 times $2,570 = $412.50
B) $122.85 times 2( 12 ) = $2,948.40
C) $2,570
D) All together it's $2,948.40 + $2,570 = $5,518.40
For D I didn't add the down payment because it's not an additional charge.
I only did the first one because I don't know if you want me to finish the rest.
Hope I helped :)
I know this one give me like 5 minutes
Answer:
I think you just turn the percent into a decimal by moving the decimal 2 numbers to the right, and multiply all the numbers
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%
