Answer: No he does not meet both of his expectation by cooking 10 batches of spaghetti and 4 batches of lasagna.
Step-by-step explanation:
Since here S represents the number of batches of spaghetti and L represents the total number of lasagna.
And, Â the chef planed to use at least 4.5 kilograms of pasta and more than 6.3 liters of sauce to cook spaghetti and lasagna.
Which is shown by the below inequality,
[tex]0.3S+0.65L \geq 4.5[/tex]Â ----------(1)
And, Â [tex]0.25S+0.8L >6.3[/tex] --------(2)
By putting S = 10 and L = 4 in the  inequality (1),
[tex]0.3\times 10+0.65\times 4 \geq 4.5[/tex]
⇒ [tex]5.6\geq 4.5[/tex](true)
Thus, for the values  S = 10 and L = 4 the inequality (1) is followed.
Again By putting S = 10 and L = 4 in the  inequality (2),
[tex]0.25\times 10+0.8\times 4 >6.3[/tex]
⇒ [tex]5.7>6.3[/tex]( false)
But, for the values  S = 10 and L = 4 the inequality (2) is not  followed.
Therefore, Antonius does not meet both of his expectations by cooking 10 batches of spaghetti and 4 batches of lasagna.
