Find the amount in an account if $45,050 is invested at 7.001% compounded quarterly, for 12 years and 3 months.
Korolek [52]
A=P(1+ \frac{r}{n})^{tr}
a=future amount
p=present amount
r=rate in decimal
n=number off time per year compouonded
t=time in years

P=45,050
r=0.07001
n=4
t=1.25

A=45,050(1+ \frac{0.07001}{4})^{(1.25)(4)}
A=45,050(1+ 0.0175025)^{5}
A=45,050(1.0175025)^{5}
A=49132.8798
round
A=$49,132.88

In the fifth grade there are 4/5 as many students who do not have glasses as those who do wear glasses if there are 60 students
Allushta [10]

Answer:

300 students

Step-by-step explanation:

Since 4/5 of students do not wear glasses, 1/5 of students do.  

There are 60 students who wear glasses, so let 'x' represent the number of students who wear glasses

(1/5)x = 60     is our equation.  "One-fifth of the number of students who wear glasses is 60"

Now solve for x

(1/5)x = 60

    x = 300    (multiply both sides by 5 to get rid of the fraction)
