Final answer:
Aunt Minnie gives you $10 per second for 4 seconds. Multiplying the rate by the time gives you a total of $40 after 4 seconds.
Step-by-step explanation:
The subject of the question is mathematics which involves a simple calculation based on a rate over time. Aunt Minnie gives you $10 per second for 4 seconds. To find the total amount of money received, you multiply the rate ($10) by the time (4 seconds).
Calculate the total amount:
$10/second × 4 seconds = $40
After 4 seconds, you would have $40.
The reference information provided seems irrelevant to this particular question, but it similarly involves simple multiplication to explain earnings based on a given rate (A) and quantity (n).
