A school is spending exactly $600 when purchasing large kits and small kits. This is described as: $600 = cost of large kits + cost of small kits.
If the school could spend up to and including $600 but no more than $600, what symbol should replace the equal sign in the equation above?
(hint: it may help to plug in amounts for the kits to figure out the answer)
<
>
Let x represent the Large Kits and y represent the Small Kits.
Choose the inequality that represents the situation.
600 >12x + 23y
Suppose the school decides to buy 20 of the large kits, How many of the small kits can the school now afford?. The school still can spend no more than $600. Let x represent the Large Kits and y represent the Small Kits.

See the word problem below.
If the person and the boxes in elevator weighed exactly 2500 lbs, the following equation would represent the situation:
2500 = weight in elevator
Since the elevator can hold a maximum of 2500 lbs, what symbol should replace the equal sign in the equation above?
Which inequality represents the number of boxes that the elevator can hold in one trip if the person is not on the elevator. Let x represent the number of 25 lb boxes and let y represent the number of 60 pound boxes.
To graph the inequality in question 26, you would first have to
solve for y to get it into y=mx+b form
put in standard form to find the y-intercept
use the weight of the boxes to find the slope
Which inequality represents the number of boxes that the elevator can hold in one trip if the person is on the elevator. Let x represent the number of 25 lb boxes and let y represent the number of 60 pound boxes.
