Griffin bought 1.2 pounds of almonds for $6.60. His friend, Sam, bought almonds for $0.70 per pound cheaper. Which equation represents the cost, c, Sam paid for x pounds of almonds?

its a straight line parallel to the time axis

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

600,000,000,000, or 6e14
