Final answer:
To find out how many minutes $10.0 will cover at a rate of 10 cents per minute, convert the dollars to cents and then divide by the per-minute cost, resulting in 100 minutes.
Step-by-step explanation:
The question is asking about a simple conversion of currency to time, based on a given rate. If 10 cents is the cost per minute, and you have $10.0, you want to know how many minutes of time that $10.0 would buy.
First, convert the dollar amount into cents to make it easier to calculate because the rate is given in cents. $10.0 is equal to 1000 cents (because $1 is equal to 100 cents, so $10 is equal to 10 x 100 cents).
Now, divide the total amount of cents by the cost per minute: 1000 cents ÷ 10 cents per minute = 100 minutes. So, $10.0 would cover 100 minutes.
