Final answer:
$10.00 at 10 cents per minute would cover 100 minutes of service.
Step-by-step explanation:
If the cost is 10 cents per minute, to find out how many minutes $10.00 would cover, first, determine how many minutes $1.00 would cover. With 10 cents per minute, $1.00 would cover 10 minutes (since $1.00 divided by 10 cents equals 10 minutes). Then, to calculate how many minutes $10.00 would cover, multiply the number of minutes covered by $1.00 (which is 10 minutes) by 10 (since there are 10 sets of $1.00 within $10.00). Therefore, $10.00 would cover 100 minutes (10 minutes multiplied by 10 sets of $1.00), allowing you to utilize the service or activity for 100 minutes based on the 10 cents per minute rate.
