Deep Cleaning Company $($DCC$)$ manufactures a powerful cleaning solvent. The main ingredient in the solvent is a raw material called

Echol. Information on the purchase and use of Echol follows.

Purchase of Echol: Echol is purchased in $20-$litre containers at a cost of $$290$ per container. A discount of $2\%$ is offered by the supplier

for payment within $10$ days, and DCC takes all discounts. Shipping costs, which DCC must pay, amount to $$350$ for an average

shipment of one hundred $20-$litre containers of Echol.

Use of Echol: The bill of materials calls for $22\mathrm{.}56$ litres of Echol per bottle of cleaning solvent. About $4\%$ of all Echol used is lost through

spillage or evaporation $($the $22\mathrm{.}56$ litres above is the actual content per bottle$).$ In addition, statistical analysis has shown that every $41$ st

bottle is rejected at final inspection because of contamination.

$1.$ Compute the standard purchase price for one litre of Echol. $($Do not round intermediate calculations and round final answer to $2$ decimal places.$)$

$2.$ Compute the standard quantity of Echol $($in litres$)$ per saleable bottle of cleaning solvent. $($Round intermediate calculations and final answer to $2$ decimal places.$)$

$3.$ Using the data from parts $(1)$ and $(2),$ prepare a standard cost card showing the standard cost of Echol per bottle of cleaning solvent. $($Round intermediate calculations and final answers to $2$ decimal places.$)$
