Question 388073
200 pounds of chemicals cost $95.
mixing vats = $400 each.
Sales tax on all products is 6% of the total cost of the order.
Shipping costs for the order will be a flat $30.


question a:


she orders 4000 pounds of chemicals.
cost per pound of chemical = $95.00 / 200 = .475
.475 * 4000 = $1900.00 for the chemicals.

Total cost for the order for 4000 pounds of chemicals only is as follows:


Chemicals = $1900.00
Shipping = $30.00
Total without Tax = $1930.00
Tax on $1930.00 at 6% = $115.80
Total Cost for the Order = $1930.00 + $115.80 = $2045.80


In equation form, this would be:


((.475 * 4000) + 30) * 1.06 = total cost of the order.


Tax is assumed to apply to the total order (material plus shipping).


question b:


Cost per vat = $400.00


y = number of vats to order.


Total cost of the order for vats only would be:


(y * 400 + 30) * 1.06
