Antonius the chef wants to cook several batches of lasagna and spaghetti for his restaurant. He plans to use at least 4.54.5 kil
yaroslaw [1]

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,

0.3S+0.65L \geq 4.5 ----------(1)

And,  0.25S+0.8L >6.3 --------(2)

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

0.3\times 10+0.65\times 4 \geq 4.5

⇒ 5.6\geq 4.5(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),

0.25\times 10+0.8\times 4 >6.3

⇒ 5.7>6.3( 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.

Parking your car near where you work costs 50¢ per hour or $4 per day. If you park for 7 hours per day, what is the LEAST that y
aleksley [76]

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
