Question

What is the value of the expression 5(500x − 50) + 50 when x = 15 ? Select one: A. 45,800 B. 37,300 C. 12,500 D. 7,500

Answer 1

The answer is 12,500 because you change the problem to

5(500x 50-50)+ 50

^ means 5 times 500 times 50 minus 50 plus 50

And round to get C. 12,500

Answer 2

B. 37,300

5(500x - 50) + 50

5([500 x 15] - 50) + 50

5(7,500 - 50) + 50

5(7,450) + 50

37,250 + 50

= 37,300
