### Brief Description

What is the real story behind all those 10-10 numbers we see advertised on TV? In this WebQuest project, students write essays to persuade their families to use a particular long-distance phone plan. Students will compare a 10-10 plan to a regular long-distance plan. They will develop equations and graphs for both of the plans and use this information to support their essay.

### Lesson Plan

Students will find the rates of a 10-10 number and one regular long-distance carrier. They will develop and graph equations for the two plans. Students will compare this information to their family's long-distance phone bill to decide which plan would be best for their family. Students will write an essay persuading their family to use a particular long-distance plan. (See a complete WebQuest lesson at http://www.gowcsd.com/master/ghs/math/furman/linsystem/call_me.htm.)

### Assessment

Evaluate students' equations, graphs, solutions by substitution and addition, and essays.
