Answer: the amount she must invest is $1852
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount invested.
P represents the principal or amount invested.
R represents interest rate
T represents the duration of the investment in years.
From the information given,
I = 2500 - P
R = 7%
T = 5 years
Therefore,
2500 - P = (P × 7 × 5)/100
2500 - P = 0.35P
0.35P + P = 2500
1.35P = 2500
P = 2500/1.35
P = 1852
Answer:
radius = 5 in
Step-by-step explanation:
Using the formula for calculating the area (A) of a circle
A = πr² ( r is the radius )
here A = 78.5, hence
3.14r² = 78.5 ( divide both sides by 3.14 )
r² = = 25 ( take the square root of both sides )
r = = 5
M=72+(-2m) is the answer to this problem
