Every week he withdraws $35 from the $950 in his savings, and he wants at least $600 by the end of the summer. So we could write:
Where 'x' is the number of weeks. Now let's solve it for 'x'.
Subtract 950 to both sides:
Divide -35 to both sides, don't forget to switch the sign when dividing/multiplying by a negative number:
So he can only withdraw at money for at most 10 weeks if he wants at least $600 left in his account.

Answer:
Step-by-step explanation:
- The product of two matrices
and
equals a matrix
, where the first element of the subscript represents the amount of files of the matrix and the second element represents the amount of columns of the matrix.
- Then, in this case
, therefore, its product will result a matrix
.
- Because C matrix is going to have an only file and three columns, we now have to find the values of the elements in each column, based on the elements of A and B.
- Commonly, to obtain the values of the resulting matrix, we just have to multiply each file of the first matrix by each column of the second matrix and sum, as follows:
- Finally, C matrix is
