kondor19780726 [428]

Answer:

58+40e−t/2458+40e−t/24

step by step explanation:

Normally, the temperature of a corpse is the temperature of the surrounding environment.

This is done by losing or gaining heat to equilibrate to that of the surrounding.

Let's assume that the final temperature of the corpse is after t hrs.

Then the temperature of the surrounding in degree Fahrenheit is equal to 58+40e−t/2458+40e−t/24

The answer and how to do it
inessss [21]
Alright, here is how to do it:
First you are going to want to multiply 4x4. [That is Dino's Charges for 4 Sandwiches.] So once you've done that, you should get 16

Now, you're going to want to multiply 8x4. [That is Carla's charges for 4 Sandwiches.] So once you've done that, you should get 24.

Now, to find the difference you will have to subtract them. 24-16 = 18.
Now that we've done this we now know your answer is:
Carla's sandwiches cost more than Dino's sandwiches. The difference is 18 dollars.
