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, 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,
----------(1)
And,
--------(2)
By putting S = 10 and L = 4 in the inequality (1),

⇒
(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),

⇒
( 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.
In this question, we're calculating how much you're going to need to pay in parking.
We know that it costs 50¢ per hour
We also know that you park for 7 hours.
Note: They're trying to trick you here with the $4 per day, you wouldn't use this information because you're not parking for the whole day.
Calculate how much you're paying per day by multiplying 7 by 0.50
7 × 0.50 = 3.5
Now, multiply how much you pay everyday (3.5) by the amount of days your'e working (5)
3.5 × 5 = 17.50
This means that you will be paying $17.50 for 5 days of parking
Answer:
$17.50
