28,000(1+ 0.05/1) 1*40

To calculate this expression, we need to follow the order of operations.

First, we calculate the term inside the parentheses: 1 + 0.05/1 = 1.05

Then, we multiply this result by 28,000: 28,000 * 1.05 = 29,400

Finally, we multiply this result by 1*40: 29,400 * 40 = 1,176,000

So, 28,000(1+ 0.05/1) 1*40 = 1,176,000.
