The cookies because if they have 100°C, after 30 seconds it loses half it‘s heat and now it only has 50°C.
After the next 30 seconds it loses again half the heat so it‘s 25°C.
You can theoretically continue this forever. It‘s exponential decay.

I’m canadian so I’m not quite sure how the money itself works, but I can explain how to do them. The easiest way is to divide each option by the number of items per price. For example, in A option 1 is already 1 ticket/ £8 whereas in the second it’s 3 tickets/ £20. So divide both the 3 and the £20 so you get the price per individual ticket. In the end you get 1 ticket/ £6.66 meaning it is a better deal than option 1.
Answer:
$84
Step-by-step explanation:
Since Chloe wants a policy for $100,000, she will pay $100,000/$25,000 = 4 times the amount shown in the table. The table amounts are for <em>monthly</em> premiums, so the <em>annual</em> amount will be 12 times that. In all, Chloe will pay annually an amount that is 4·12 = 48 times the amount in the table.
As a female smoker, she will pay annually for a $100,000 policy ...
48 · $5.25 = $252.00
If Chloe were a non-smoker, she would pay annually ...
48 · $3.50 = $168.00
If the insurance company considers a smoker who quits to be a non-smoker, then by quitting, Chloe could save ...
$252 -168 = $84 . . . annually
_____
<em>Alternate means to the end</em>
Of course, it is easier to multiply the difference in rates by 48:
48·($5.25 -3.50) = 48·$1.75 = $84 . . . . annual savings
