ANTONII [103]

Answer:

Supplier A: 5.25 per bushel and deliver fee of 3 per bushel

Supplier B: 6.50 per busher and flat delivery fee of $1500 each week

500 bushels of grain each week.

Supplier A: 5.25x + 3x = 5.25(500) + 3(500) =  2,625 + 1,500 = 4,125

Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750

Supplier B would cost more if the company buys 500 bushels of grain per week.
