Answer

Explanation:

Step1: Check option A

For (x = 10) and (y=5), first check (200x + 150y): (200\times10+150\times5=2000 + 750=2750>2640), so option A does not satisfy (200x + 150y\leq2640).

Step2: Check option B

For (x = 7) and (y = 7), (x + y=7 + 7=14<15), so option B does not satisfy (x + y\geq15).

Step3: Check option C

For (x = 6) and (y = 11), (200x+150y=200\times6 + 150\times11=1200+1650 = 2850>2640), so option C does not satisfy (200x + 150y\leq2640).

Step4: Check option D

For (x = 5) and (y = 10), (200x+150y=200\times5+150\times10=1000 + 1500=2500\leq2640) and (x + y=5 + 10=15\geq15).

Answer:

D. 5 scarves and 10 hats
