At the beginning of the month, Joe has $180 in his bank account. He wants to buy a new gaming system for $250 in two weeks. His parents have offered to loan him money if he needs it. He gets $20 a week for an allowance. Will he have enough money at the end of two weeks to make the purchase on his own? If not, how much will he have to borrow from his parents? Explain.

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

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
