Answer:
Step-by-step explanation:
A jewelry store is having a going-out-of-business sale. Therefore, all merchandise is marked 40% off the regular price.
The regular price of a watch is 59.95 dollars. This means that the amount of the discount would be
40/100 × 59.95 = 0.4 × 59.95 = $23.98
Therefore, the sale price of the watch would be the difference between the regular price and the amount of the discount. It becomes
59.95 - 23.98 = $35.97
The answer above is right that’s the answer

Answer:
1) a. False, adding a multiple of one column to another does not change the value of the determinant.
2) d. True, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other.
Step-by-step explanation:
1) If the multiple of one column of a matrix A is added to another to form matrix B then we get: |A| = |B|. Here, the value of the determinant does not change. The correct option is A
a. False, adding a multiple of one column to another does not change the value of the determinant.
2) Two matrices can be column-equivalent when one matrix is changed to the other using a sequence of elementary column operations. Correc option is d.
d. True, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other.
