Answer:
$25
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Present value = $100
Interest rate = 5% per year
So, Total amount after 5 years = P (1+rt)
Where, P = present value, r = rate , t = time
So, total amount after 5 years = $100 ( 1 + (0.05 × 5))
= $100 × 1.25
= $125
Now interest earns = Total amount after 5 years - Present value
= $125 - $100
= $25
Answer:
1/2 mph
Step-by-step explanation:
Given :
Distance traveled, D = 12 miles
Upstream Swim time = 4 hours
Return swim time = 3 hours
Upstream rate = 12/4 = 3 mph
Return rate = 12/3 = 4 mph
Let
swim rate = s
Current rate = c
s - c = upstream rate
s + c = return rate
s - c = 3 - - - (1)
s + c = 4 - - -(2)
From (1)
s = 3 + c
Put into (2)
3 + c + c = 4
3 + 2c = 4
2c = 4 - 3
2c = 1
c = 1/2 mph
Hence, rate of current = 0.5mph
N = regular rate
1.4n= overtime rate
30n + 5(1.4n) = $436.60 (30 hours x regular rate n) plus 5 hours at 1.4 times reg rate.
30n + 7n = $436.60 now add like terms
37n = $436.60 now divide both sides by 37
n= $11.80
Check to see if my answer is reasonable 30 x 12= 360 + 5 x 10 x 1.4 = about 70 (notice that I used 10 instead of 12 here so I could do it in my head)
360 + 70 = 430 - close enough - my answer is reasonable
Check:
(30 x $11.80) + 5 ( 1.4 x 11.80
354 + 5( 16.52)
354 + 82.60 = 436.60 ($436.60)
Answer:
27
Step-by-step explanation:
3/1=x/9
cross multiply, or its just a ratio actually. 1:3 is equal to 9:27
