Bot GPT 3.5 To solve for x, we can start by distributing 0.60 to both terms inside the parentheses on the left side of the equation:
x + 0.60(15) = 0.80(x + 15)
x + 9 = 0.80(x + 15)
Next, we can distribute 0.80 to both terms inside the parentheses on the right side of the equation:
x + 9 = 0.80x + 0.80(15)
x + 9 = 0.80x + 12
Now, we can subtract 0.80x from both sides of the equation to isolate the x term:
x - 0.80x + 9 = 0.80x - 0.80x + 12
0.20x + 9 = 12
Subtract 9 from both sides of the equation:
0.20x + 9 - 9 = 12 - 9
0.20x = 3
Finally, divide both sides of the equation by 0.20 to solve for x:
(0.20x)/0.20 = 3/0.20
x = 15
Therefore, the solution is x = 15. Answer choice D is correct.
