No of pizzas sold

P= cheese bacon 'shrooms

{231 182 168}

{241 206 132}

No of pizzas sold

D= Revenues Advertising fees

[ 2.69 .23 ]

[ 2.71 .25 ]

[ 2.84 .29 ]

*If matrix K is the product of p and d, which elelment in matrix k represents the total advertising fees for week one?*
K= (P)(D)=

[ P11 P12]

[ P21 P22]
