Calculate the cost (omit commission) of buying the 500 shares of Delta Air at $50.61.
galben [10]

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The cost of 500 shares of Delta Air is $25,305.

<h3>What is multiplication?</h3>

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The cost of a single share is $50.61, therefore, the cost of 500 shares will be,

Cost of 500 shares = 500 × cost of single share

                                 = 500 × $50.61

                                 = $25,305

Hence, the cost of 500 shares of Delta Air is $25,305.
