You can have 6 gallons of gas and 6 gallons of diesel.

Answer:

(12,1.625)

Step-by-step explanation:

Gas costs $6 per gallon

Cost of x gallons gas = $6x

Diesel costs $8 per gallon

Cost of y gallons gas = $8x

You have at most $85 to spend on fuel.

So, equations becomes : \(6x+8y\leq 85\)

You must purchase at least 12 gallons of gas for your car

\(\Rightarrow x\geq 12\)

So, by plotting graph , we get the possible solution .

Solution : (12,1.625)
