Answer :
The equation that can be used to determine the number of cells after x hours is; y = 0.5x + 30.
Linear model Equations
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.
