Answer:
240$
Step-by-step explanation:
we know that
The simple interest formula is equal to
I=P(rt)
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
Sandra
t = 1 year
I= $75
P= $2,500
r= ?
substitute in the formula above
75=2,500 (r(1))
solve for r
r=75/2,500)
r= 0.03
Convert to percentage form
r= 0.03 * 100 = 3%
Ron
t=1 year
I = ?
P= 8,000
r= 0.03
substitute in the formula of interest
I = 8,000(0.03 *1)
I = $240

Answer:
Step-by-step explanation:
Pythagoras theorem
a^2=b^2+c^2
(x-2)^2=9^2+(x+1)^2
x^2-4x+4=81+x^2+2x+1
Collect like terms
-4x-2x=82-4
-6x=78
x=-13
Answer:
(2.5*(30/5)+6)*12=252
Step-by-step explanation:
Answer: $11,155
Step-by-step explanation: For this problem, first we will use the "Simple Interest" equation to find the total interest earned after three years.
First, convert 3.85% to a decimal, 0.0385.
I, interest = 10,000 x 0.0385 x 3
I = 1,155
Now add the total interest $1,155 to the total deposit $10,000.
1,155 + 10,000 = $11,155
