Answer: No. You cannot multiply the matrices in any order. A*B is not defined. Also, B*A is not defined.
------------------------------------------------------------------------
Explanation:
Matrix A has 1 row, and 4 columns.
Matrix B has 3 rows, and 4 columns
In order for A*B to be possible, A has to have the same number as columns as B has rows. In other words, the inner dimensions have to match up. The '4' in '1x4' needs to match up with the '3' in the '3x4'. This match doesn't happen.
The same story happens with B*A, just things have been flipped.
B has 3 rows, 4 columns
A has 1 row, 4 columns
The "4 columns" of B does not match with "1 row" of A.
7. 150 students
8. 320 bags
9. 600 families
10. 160 diners
Set up an equation for each store by multiplying the cost of the basketball by the number of basketballs bought (b) and add the cost of the hoop:
Hoops House: total = 20b + 200
Baller Basement: total = 15b + 250
Now to solve for b, set the two equations equal to each other:
20b + 200 = 15b + 250
Subtract 15b from both sides:
5b + 200 = 250
Subtract 200 from both sides:
5b = 50
Divide both sides by 5:
B = 10
The answer is 10 basketballs
