How Matrices Can Help When You’re Dating On A Budget.



How Matrices Can Help When You’re Dating On A Budget.


The scenario was that each student was treating their partner out on a date for pizza with the only caveat being they were on a tight budget and needed to find the cheapest place to take their date.


I first had my student draw a picture of their dates!
 


(Eva didn't talk much)



The students were asked to skim through three restaurant take-out menus to find the price of a large pizza and placed the prices inside a 1 x 3 matrix (Matrix A).
 
Next, the students were asked to skim through three restaurant take-out menus to find the price of additional toppings for a large pizza and placed the prices inside another 1 x 3 matrix (Matrix B).




Next, I had each student ask their date how many toppings they wanted on their large pizza (I answered for their dates of course).

 

The students then multiplied matrix B by the number of toppings they wanted on their pizza and placed the prices inside another 1 x 3 matrix (Matrix C).

 

Finally, the students were asked to add Matrix A to Matrix C to find the total price at three restaurants for a large pizza with a specified number of toppings and choose the cheapest restaurant.
