quoted interest rate of 4.2% by 0.125% per point purchased. Each point will cost
1% of the amount borrowed. What will be the cost to purchase 2 points?
$9,600
$6,000

$12.000

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

add 8+12 to get a simplified answer of 12r-20
