If you invest in $1600 at 5.25% for 18 months, how much simple interest is earned

$126

Step-by-step explanation:

P=$1600

R=5.25%

T=18/12=3/2

NOW

WE HAVE,

S.I=PTR/100

=(1600*3/2*5.25)/100

=25200/200

=$126

HENCE,$126 is earned.

step-by-step explanation:

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
