Answer:
$8
Step-by-step explanation:
The equation that can be used to determine the number of cells after x hours is; y = 0.5x + 30.
<h3>Linear model Equations</h3>
It follows from the task content that;
- The scientist starts with a sample of 30 bacteria cells, it follows that the intercept of the linear model is 30.
Additionally, since the number of bacteria cells increases by 50% every hour implies that the rate of change, slope of the equation is 0.5.
Hence, the required equation is; y = 0.5x + 30.

Divide the range by the number of marks: [9682192 - 1010020] / 10 = 867.217
So a reasonable scales is millions and the marks will be, 1 million, 2 million, 3 million, 4 million, ... until 10 million
