Question 10 (Mandatory) (1 point) Consider a manufacturing process that produces 5000 units at a cost of $600,000 and 10,000 units at a cost of $800,000. Each unit produced can be sold for $100. Assume a linear relationship exists between the number of units produced and cost. Find the average cost per unit of producing 50,000 units. () $1,000 () $480 () $2,400,000 () %48 Question 11 (1 point) The cost of tuition at a community college is given by y = 450 + 69x, where x is the number of credit hours. Find and interpret the y-intercept of the graph of this function. O 450; The tuition increases by $450 for each additional credit hour. O 69; There is a tuition fee of $69 in addition to the charge per credit hour. O 450; There is a tuition fee of $450 in addition to the charge per credit hour. O 69; The tuition increases by $69 for each additional credit hour. Question 12 (1 point) The population of a small town can be modeled by y = -34t + 13,500, where t is the number of years since 2010. Interpret the y-intercept of the graph of this function. O The population of the town is increasing by 34 people per year. O The population of the town is decreasing by 34 people per year. O The population of the town was 34,000 in 2010. O The population of the town was 13,500 in 2010. Question 13 (1 point) The cost of manufacturing a molded part is related to the quantity produced during a production run. When 100 parts are produced, the cost is $300. When 400 parts are produced, the cost is $2700. What is the marginal cost of the function? (") $6.00 per part () $8.00 per part (") $9.00 per part () none of above Question 14 (1 point) The relationship between the number of units sold by a company and the profit is linear. If 2 units sold results in $342 profit and 42 units sold results in 1596 profit, find the marginal profit. () $38 per unit () $19 per unit () $76 per unit () none of above Question 15 (1 point) Suppose the monthly cost for manufacturing bar stools is C(x) = 33x + 503, where x is the number of bar stools produced each month. Find and interpret the marginal cost for the product. O $503 per bar stool; Manufacturing one additional bar stool increases the cost by $503. O $503 per bar stool; Manufacturing one additional bar stool decreases the cost by $503. Q iSS per bar stool; Manufacturing one additional bar stool increases the cost by 33.
