Answer:

Step-by-step explanation:

The inside of a refrigerator is 17 x 18 x 42 inch, to calculate the samples that would fit in the refrigerator is calculating the volume which is length x breadth x height

You can opt to calculate the volume in inch ^3 or cm^3

Both will be discussed here

In inch^3

Volume= 17 × 18 × 42 = 306 x 42= 12852in ^3

In cm^3

Convert inch to cm

I inch is 2.54cm

17 inch = 43.18cm

18 inch = 45.72cm

42 inch = 106.68cm

Volume = 43.18 × 45.72 × 106.68 = 210606.546528cm^3

210606.55cm^3 approximately

Natali [406]

Answer:

383 children and 361 adults

Step-by-step explanation:

Let's say there are a adults and c children. Since the total number of people was 744, we can write:

a + c = 744

We also know that children's prices are $1.75 per child and adults' prices are $2 per adult. Since the total is $1392.25, we can write:

1.75c + 2a = 1392.25

Now we have a system of linear equations:

a + c = 744

1.75c + 2a = 1392.25

Multiply the first equation by 2:

2 * (a + c = 744)  ⇒  2a + 2c = 1488

Now subtract the second equation from this one:

    2a + 2c = 1488

-    2a + 1.75c = 1392.25

___________________

    0a + 0.25c = 95.75

c = 383

Plug this in to find a:

a + c = 744

a + 383 = 744

a = 361

There were 383 children and 361 adults.
