Final answer:
The equation for the time to produce personalized chocolate bars is y = 0.09x + 35.25, with a slope of 0.09 and a y-intercept of approximately 35.25.
Step-by-step explanation:
To find an equation for the time it takes to produce personalized chocolate bars, you need to calculate the slope (m) and the y-intercept (b) from the given data points. According to the information, the slope is approximately 0.09. Using the sums provided for the median x and y values (1264 and 219.5 respectively), and the calculated slope, we can find the y-intercept through the formula b = y - mx, which translates to b = 219.5 - 0.09(1264). This simplifies to b ≈ 35.25. Therefore, the equation of the line representing the time to produce personalized chocolate bars is y = 0.09x + 35.25.
