Answer to Problem 86AYU
The matrices that represent the sales data for city and suburbs for month of January and Februaryare
Explanation of Solution
Given information:
The Rizza Ford sold 400 subcompact, 250 intermediate-size cars and 50 SUV’s in the city location and 450 subcompact, 200 intermediate-size cars and 140 SUV’s in suburbs for the month of January.
The Rizza Ford sold 350 subcompact, 100 intermediate-size cars and 30 SUV’s in the city location and 350 subcompact, 300 intermediate-size cars and 100 SUV’s in suburbs for the month of February.
Calculation:
Consider the provided information that the Rizza Ford sold 400 subcompact, 250 intermediate-size cars and 50 SUV’s in the city location and 450 subcompact, 200 intermediate-size cars and 140 SUV’s in suburbs for the month of January.
The Rizza Ford sold 350 subcompact, 100 intermediate-size cars and 30 SUV’s in the city location and 350 subcompact, 300 intermediate-size cars and 100 SUV’s in suburbs for the month of February.
The above data can be represented as a
The representation for sales for month of January is,
The representation for sales for month of February is,
To calculate: The total sale done in January and February.
Answer to Problem 86AYU
The total sale done in January and Februaryis
Explanation of Solution
Given information:
The representation for sales for month of January is,
The representation for sales for month of February is,
Calculation:
Consider the representation for sales for month of January is,
The representation for sales for month of February is,
Therefore, total sales done in month of January and February is the sum of the above matrices ,
Therefore, total sale done in January and Februaryis
