In matrix C , a coffee shop records the cost to produce a cup of standard Columbian coffee andhe cost to produce a cup of hot chocolate Matrix P contains the selling prices to the customer. Small Medium Large coffee Chocolate C = [ $0 .90 $0 .84 $1 .26 $1 .15 $1 .64 $1 .50 ] Small Medium Large coffee Chocolate P = [ $3 .05 $2 .25 $3 .35 $3 .05 $4 .15 $3 .65 ] Compute P - C and interpret the result. b. If the tax rate in a certain city is 7%, use scalar multiplication to find a matrix F thatgives the final price to the customer (including sales for both beverages for each size. Round each entry to the nearest cent.
