The correct answer should be: Eight years. To get ½ of the 300, you need 0.5^(t/8) to equal ½, or 0.5. That means that the exponent must be 1. This happens when t = 8 years.
You can use the distance formula for this:
√(x2-x1)²+(y2-y1)²
so you'll get √(1-4)²+(11-7)² = √(-3)²+(4)² = √9+16 = √25 = 5 and 5 is your answer
5x + 3 = 38
5x = 38 + 3
5x = 35
x = 35/5
x = 7
