The most cost-effective way to buy them is according to Option B

Option B: 100 sheets at a time for $800

Step-by-step explanation:

We are given that building contractor needs 500 sheets of drywall

A)50 sheets at a time for $600

Cost of 50 sheets = 600

Cost of 1 sheet =

Cost of 500 sheets =  

                                =  

Thus cost of 500 sheets is $6000 according to option A.

B)100 sheets at a time for $800

Cost of 100 sheets =800

Cost of 1 sheet =

Cost of 500 sheets =  

                                =  

Thus cost of 500 sheets is $4000 according to option B.

C)250 sheets at a time for $2,500

Cost of 250 sheets =2500

Cost of 1 sheet =

Cost of 500 sheets =  

                                =  

Thus cost of 500 sheets is $5000 according to option C.

D)500 sheets at a time for $4,500

Thus cost of 500 sheets is $4500 according to option D.

Hence the most cost-effective way to buy them is according to Option B.

Option B: 100 sheets at a time for $800

aloha~! my name is zalgo and i am here to you out on this gracious day. in order to compare the ratios easily, it is best that we simplify the question first. so, the cougars would have 6 wins for 5 losses, bobcats make 2 wins for 1 loss. bulldogs and tigers have a ratio where you can't simplify it. so, the team with the lowest rate would be the bobcats.

i hope that this ! : d
