2 math books and 6 science book
70×2=140 50×6=300
300×140=$440
Theres not really any way to tell because the cost per widget is highest when making three, lowest when making 7, but then increases when making 12. If the cost didnt rise when making 12 and instead followed the trend of the more widgets you make, the cheaper it is per widget

The value of the matrix X is
<h3>How to solve for matrix X?</h3>
The attached image represents the complete question
The given matrices are:
The expression is given as:
A(X - B) = C
Expand
AX - BX = C
This gives
Evaluate the products
Evaluate the difference
By comparing the positions, we have:
6a - 4c = -1
6b - 4d = 2
4a - 4c = -2
4b - 4d = 2
Rewrite as:
6a - 4c = -1 and 4a - 4c = -2
6b - 4d = 2 and 4b - 4d = 2
Using a graphing tool, we have:
a = 0.5, c = 1, b = 0, and d = -0.5
Hence, the matrix X is:
