Answer:
The equation is
n = PRT/100
The value of p
p = $1250
Step-by-step explanation:
Simple interest= n
Rate of interest = r
Number of years = t
Then principal amount= p
This p can be said to be the constant of the equation because it's value never changes
n = $225
r = 4.5%
t = 4 years
The interest varies jointly with the rate, the time and the principal amount.
The equation for the relationship
n > prt
But r is in percentage
n = PRT/100
For the value of p
p =(225*100)/(4.5 *4)
p= 22500/18
p= 1250
p = $1250
Answer:
3rd Matrix
Step-by-step explanation:
When you start putting the coefficients in as the matrix, you see that -9 has to be the 1st number, so that eliminates choice B and choice D as answers. You are left with choices A and C. C is the correct choice because when you plug in the second equation, your coefficient is -5, not 0.
