A local farmer sells small bales of hay to several different rancher supply stores. The table below shows the number of bales of hay ordered by each store and the cost of the order.
Number of Cost of the
Bales of Hay Order
150 $2,550
85 $1,445
120 $2,040

If another store wants to order 250 bales of hay, what will be the cost of the order?
O A
$4.000
OB.
$4,500
О с.
$3.825
OD
$4,250
