Suppose $1,000 is put into an account that pays simple interest at a rate of 3.5% annually. What is the value of t if the money is deposited for 212 years? A. 0.25
B. 1.5
C. 2.0
D. 2.5

Step-by-step explanation:

Formula:

I = Prt

I - interest

P - initial value

r - interest rate  

t - time (years)

Solution:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

no
