Final answer:
The total daily cost, C, of producing x golf clubs can be found using the equation C = 7.5x + 4988. The graph of the total daily cost for 0≤x≤200 is a straight line with slope 7.5 and y-intercept 4988. The slope represents the additional cost incurred for each additional golf club produced, and the y-intercept represents the fixed cost.
Step-by-step explanation:
(A) To find the total daily cost, C, of producing x golf clubs, we can use the equation of a line. Let's assume the equation is given by C = mx + b, where m is the slope and b is the y-intercept. We can find the values of m and b using the given information:
1. When the plant manufactures 50 golf clubs per day, the total daily cost is $5363. This gives us the point (50, 5363).
2. When the plant manufactures 80 golf clubs per day, the total daily cost is $7613. This gives us the point (80, 7613).
Now we can use these two points to find the values of m and b. First, let's find the slope:
m = (y2 - y1) / (x2 - x1) = (7613 - 5363) / (80 - 50) = 225 / 30 = 7.5
Next, let's substitute the values of one of the points into the equation to find b:
5363 = 7.5 * 50 + b
b = 5363 - 7.5 * 50 = 5363 - 375 = 4988
So the equation for the total daily cost, C, of producing x golf clubs is C = 7.5x + 4988.
(B) To graph the total daily cost for 0≤x≤200, we can substitute different values of x into the equation C = 7.5x + 4988 and plot the corresponding values of C. The graph will be a straight line with slope 7.5 and y-intercept 4988.
(C) The slope of the cost equation, 7.5, represents the additional cost incurred for each additional golf club produced. The y-intercept of the cost equation, 4988, represents the fixed cost or the cost of production even when no golf clubs are produced.
