Matrices Matrix P shows the no. of pizzas a local pizza parlor sold over a 2 week period. Matrix D shows the revenues of and advetising fees in dollars per pizza.
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]
I'm guessing that this is more of a basic matrices knowledge question..
Either that or i'd have to multiply the matrices by hand -yuck, how tedious-and choose an answer based on the looks of things.
