Step-by-step explanation:

Giving the following information:

Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each.

To calculate the number of text messages, we need to use the following formula:

Total cost= 39 + 0.15x

x= number of text messages

55.05= 39 + 0.15x

16.05= 0.15x

107= x

Luis incurred 107 extra text messages.

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.
