Question

Davina is comparing cell phone plans. The first plan has a flat fee of $10 plus .04 per text. The second has a flat fee of $5 plus .12 per text. What is the difference in dollars for the two plans with 15 text messages per month after 6 months.

Use a problem solving model to solve the problem.

Answer 1

10+.04(15)(.5)=10.30. 5+.12(15)(.5)=5.9. 10.3-5.9=4.4 the difference is 4.40 :)
