2.) Your father uses text messaging to communicate with his employees. If he sends an average of 19 text messages each day, how many more text messages does he send than you? Write an equation and solve for the unknown value.

3.) Your parents allow you to have Internet access on your cell phone as long as you prepay the bill. If your bill is $17.50 per week, how much would you have to save per day to pay the bill? Describe the step-by-step process you use to solve the problem.

Answer 1

Answer: 1. 26-12=14

2. 19-12=7

3. 17.50 divided by 7=2.5

Explanation:

Answer 2

1) Let's make sure we understand the word problem first. You send 12 texts a day, and your older sister sends more texts than you do. So overall you and your sister together send 26 text messages per day, which indicates subtraction.

26 - 12 = 14.

Your sister sends 14 texts per day.

2) So I'll assume you are connecting this to the problem above. Your father sends 19 messages per day, and u send 12 messages per day. HOW MANY MORE indicates subtraction.

19 - 12 = 7.

Your father sends 7 more texts than you do per day.

3) Alright, lets problem. The bill per week is $17.50, and there is 7 days in a week. So lets divide 7 by $17.50 since we need to know how much to save up per day.

17.50 ÷ 7 = $2.5.

You need to save $2.5 per day to pay the bill.
