A linear programming computer package is needed.

gasolines, the percentage of important ingredients in each type of crude oil differs, as does the cost per gallon. The percentage of ingredients A and B in each type of crude oil and the cost per gallon are shown.

How many gallons of each type of crude oil should be used in the two gasolines to satisfy daily demand at a minimum cost? $($Round your answers to the nearest gallon.$)$

gallons of crude $1$ used to produce regular

gallons of crude $1$ used to produce high$-$octane

gal

gallons of crude $2$ used to produce regular

gallons of crude $2$ used to produce high$-$octane

What is the total minimum cost $($in $ $)$ for the gallons? $($Round your answer to the nearest dollar.$)$
