Answer:
Step-by-step explanation:
let x = # of hats
let y = # of jackets
Parameters:
x + y >_ 250 (at least (greater than or equal to) 250 items in total)
Rearranged (by subtracting x from each side. It's implied that m = -1):
y >_ - x + 250
x >_ y (at least (greater than or equal to) as many hats as jackets)
Rearranged (just reverse the order it's written in now. It's implied that m = 1, b = 0):
y >_ x
5x + 8y <_1500 (5$ per hat, plus 8$ per jacket, for a total of 1500$ or less (lesser than or equal to))
Rearranged (by subtracting 5x from each side, then dividing the whole thing by 8)
y <_ - (5/8)x + (375/2)
