The controller of Moonshine has requested a quick estimate of the manufacturing supplies needed for July when production is expected to be 470,000 units. Below are actual data from the prior three months of operations:

	Production in units	Manufacturing supplies
March	450,000	$723,060
April	540,000	853,560
May	480,000	766,560

Using these data and the high-low method, what is the best estimate of the cost of manufacturing supplies that would be needed for July? (Assume that this activity is within the relevant range.)

a.

$755,196

b.

$752,060.

c.

$781,060.

d.
