Answer:
A*B=
Step-by-step explanation:
Given A= = B
Finding A*B means multiplying the first row with the first column and first row with the second column would give the first row elements. The second ro0w elements are obtained by multiplying the second row with the 1st column and second row with the second column.
so A*B=
Now multiply and add the separate elements of the matrix A*B=
A*B=
b. The 1st element of the 1st row shows the salaries of the managers and 2nd element of the 1st row the salaries of associates at the restaurant . The second row 1 st element shows the benefits of the managers and 2nd element the benefits of the associates at the food truck.
c. The total cost of salaries for all employees (managers and associates) at the restaurant = 705 + 80 = 785
Total cost of benefits for all employees at the food truck= 121 + 14= 135

Complete question is given below;
Tracy had a total of $200 to spend while shopping. She has already spent $122 on clothes. She wants to buy some video games that are on sale for $20 each, including tax. Enter the maximum number of video games Tracy can buy with the remaining money.
Answer:
Tracy can buy maximum of 3 video games with the remaining money.
Step-by-step explanation:
Given:
Total money to spend on shopping = $200
Money spend on clothes = $122
Cost of each video game = $20
We need to find the number of Video games she could buy.
Solution:
Let the number of video games be 'x'.
So we can say that;
Money spend on clothes plus Cost of each video game multiplied by number of Video games should be less than or equal to Total money to spend on shopping.
framing in equation form we get;
Now by subtraction property of Inequality we will subtract both side by 122 we get;
Now dividing both side by 20 using division property of inequality we get;
Hence Tracy can buy maximum of 3 video games with the remaining money.
