Felix’s feed mill sells chicken feed for $8.00 per bag. this price is no longer high enough to create a profit. felix decides to raise the price. he is considering four different plans. plan a: raise the price by $0.10 each week until the price reaches $12.00. plan b: raise the price by 10 percent each week until the price reaches $12.00. plan c: raise the price by the same amount each week for 8 weeks, so that in the eighth week the price is $12.00. plan d: raise the price by $0.25 each week until the price reaches $12.00. which plan will result in the price of the feed reaching $12.00 fastest?

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
