The annual return percentages will be evaluated using the formula:
A=P(1+r/100)^n
where:
A=amount
P=principle
r=rate
n=time
a] A=$500, P=$400, n=1 years
500=400(1+r)^1
solving for r we shall obtain:
1.25=1+r
hence
r=1.25-1
r==0.25
annual rate of investment is 25%
b] A=2500+100=$2600, P=$ 2000, n=1 year
hence
2600=2000(1+r)^1
2600/2000=1+r
1.3=1+r
r=1.3-1
r=0.3
annual rate of investment is 30%
It would be 2/4. 2/4 simplifies to 1/2.
Answer:
He will have to shovel at least 11 driveways
Step-by-step explanation:
He gets 7$ for each drive way, so if he shovels 10, 10 x 7= 70$, But he still needs 5 more dollars, so he will need to shovel an extra driveway so that he can get 75$ he will have 2$ extra
Rida:
5 1/2 :77
5.5 : 77
Divide both sides by 5.5 to get $/hour:
1:14
Elisa:
3 3/4:60
3.75:60
Divide both sides by 3.75 to get $/hour:
1:16
16 is bigger than 14 so Elisa earns more.
