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 : [tex]6x+8y\leq 85[/tex]
You must purchase at least 12 gallons of gas for your car
[tex]\Rightarrow x\geq 12[/tex]
So, by plotting graph , we get the possible solution .
Solution : (12,1.625)
