Greg is considering a text message plan that advertises: "A one-time joining fee of $3.00 and $0.08 per message."

1. Write an explicit formula for the text messaging plan. 2.Greg knows he sends and receives about 1800 texts per messages per month. Use an example and other mathematical evidence to show if this is a good deal.

I believe the answer to 1. is: 3+ 0.08. I'm clueless about 2. HELP!

fee=.08m+3.00

fee=.08*1800 + 3=147

Thank you!

1. The explicit formula for the text messaging plan can be written as:

Total Cost = One-time Joining Fee + (Cost per Message * Number of Messages)

In this case, the one-time joining fee is $3.00 and the cost per message is $0.08. Therefore, the explicit formula would be:

Total Cost = $3.00 + ($0.08 * Number of Messages)

2. To determine if the text messaging plan is a good deal for Greg, we need to compare the total cost of this plan to the potential cost of other plans. Let's calculate the total cost for Greg, assuming he sends and receives about 1800 text messages per month.

Total Cost = $3.00 + ($0.08 * 1800)
Total Cost = $3.00 + $144.00
Total Cost = $147.00

Therefore, the total cost for Greg with this text messaging plan would be $147.00 per month.

To determine if this is a good deal, we need to compare it with other plans available in the market. Look for other text messaging plans that offer similar features (such as the number of messages) and calculate their total cost. Then, compare those costs with the total cost of the plan in question. The plan with the lowest total cost would be the better deal.

For example, if Greg finds another plan that offers the same number of messages for a total cost of $140.00 per month, then the other plan would be a better deal, as it would save him $7.00 per month compared to the initial plan.

It is important for Greg to evaluate different plans and consider his texting habits before deciding which plan is the best and most cost-effective for him.
