8. Ms. Kennedy wants to buy a new interactive whiteboard for her classroom that costs $989. So far,
Ms. Kennedy has collected $485 in donations, and
$106 in fundraising. About how much more money
does she need to buy the interactive whiteboard?

$398

Step-by-step explanation:

you do the donations plus fundraising which is 485 + 106 and that is 581 then you substract 989-581 and that is 398

so the answer is $398

answer: do you still need this?

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
