Procedure

Students should write the algebraic equation from

the pattern showing in their table: M = P x 11.50 or

using implicit multiplication, M = 11.50 P.

Students check their formula using the data editor

(

v) on the TI-30XS MultiView™ calculator, as in

the warm up example.

1. Have the students check to see how the calculator

is set up.

2. Enter the first three values in L1 {1, 2, 3}.

3. Translate your formula to the calculator formula

and enter the formula into L2.

Your formula: M = ____________________________

The calculator formula: L2 = ___________________

4. Enter more values into L1 to check the table of

values and the formula. This activity validates

the formula for several values.

5. Enter 7500 in L1 to find the amount of money in

L2. Write the math as

M = 11.50 x 7500 = $86,250.

6. Create a report by filling in a table of values and

a graph. Write a paragraph describing the work

for the presentation.

Answers in the paragraph will vary. Make sure

that the students explain the table, graph, and

algebraic sentence (formula) in the paragraph.
