A) C + S = 300
B) S -C = 110
Adding A and B we get:
2 S = 410
Soybeans = 205 acres
Corn = 95 acres
18 students are 100%-37,5%-40%=22,5%
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is.
SO:
x students - 100%
(22 + 1/2)x =18×100
(22 + 1/2) can be represented as just 25.5
-//- = 1800
we need to divide bot sides by 25.5
x = 1800 / 25.5
... x = 80
Multiply hourly rate by hours worked:
Saturday 7 hours x 9.00 = 63.00
Sunday: he gets paid 1 times his rate: 9.00 x 1 = 9.00
Multiply by hours : 9.00 x 4 = 36.00
Add the days together: 63 + 36 = 99.00
He earned 99.00
T(6) = 0.009 * 6
t(6) = 0.054
Answer:
It takes an account 5.4 years to earn $178.25 in interest with an annual interest rate of 5%.
Step-by-step explanation:
You can use the following formula to calculate the time it takes an account to earn a certain amount in interest:
t=(1/r)*((F/P)-1), where:
t= time
r= rate of interest= 5%
F= future value= 650+178.25=828.25
P= present value= 650
Now, you can replace the values on the formula:
t=(1/0.05)*((828.25/650)-1)
t=20*0.27
t=5.4
According to this, the answer is that it takes an account 5.4 years to earn $178.25 in interest with an annual interest rate of 5%.
