Answer:

The answer would be D: y=366x

Explanation:

The question asks for an equation that says how many messages she sends in x amount of weeks.

First, you would need to find how many messages she sends in 1 week. She sends 12 messages in a 4-hour span (4 pm to 8 pm) so that makes 48 messages in that span a day. Then you multiply that by 7 to see how many she sends in a week.

y represents the total number of messages, this is unknown. X represents the number of weeks.

Hope this helps :)

Answer: D

Explanation:

Stacie sends text messages for 4 hours each day (from 4 p.m. to 8 p.m.), so she sends a total of 12 x 4 = 48 text messages per day.

To calculate the number of text messages that Stacie sends during these hours in x weeks, we need to multiply the number of days by the number of text messages per day.

Since there are 7 days in a week, Stacie sends 48 x 7 = 336 text messages per week.

Therefore, the equation that can be used to calculate the number of text messages that Stacie sends during these hours in x weeks is:

y = 336x

So the answer is D.
