Answer:
0.75
Explanation:
Marginal Propensity to Consume (MPC) is the change in consumption due to change in income
Change in consumption = $7,250 - $6,500 = $750
Change in income = $11,000 - $10,000 = $1,000
MPC = Change in consumption / Change in income
MPC = 750 / 100
MPC = 0.75
Answer:
Consumer surplus decreases by $180.
Explanation:
Current consumer surplus = $25 * 90 unit = $2250
If the price of goods drop to $23 then the new consumer surplus will be
$23 * 90 units = $2070
The change in consumer surplus is $180 .
Answer:
Explanation:
a. Rolling resistance factor = 100 lb/ton for hauling as well return path Grade for haul route = 5%. Grade for return route = 0 From Table 14.2 – rutted dirt road – rolling resistance factor = 100 lb/ton, Rolling resistance on haul route = 100(75) = 7,500 lbs Rolling resistance on return route = 100(50) = 5,000 lbs Grade resistance, GR = % grade 20lb/ton/%grade weight on wheels (tons) Grade resistance on haul route = 5 × 20 × 75= 7,500 lbs
b. Effective (Equivalent) Grade = RR% + GR% To convert rolling resistance, RR into rolling resistance factor, RR%, divide rolling resistance by 20 (see section 14.5 in the text book) and therefore; Effective grade = + grade Effective grade while hauling = + 5 = 10% Effective Grade while returning = + 0 = 5%.
c) Considering the cycle time of the pusher and the scrapers, Scrapers to be used = = 6.4 The motivation is to keep the pusher busy all the time instead of waiting for the scraper to return If 6 scrapers are used, the pusher will be idle and the cost will be lower (since we will have 6 scrapers and 1 pusher). So is the productivity. If 7 scrapers are used, the scrapers will be idle and the productivity will be higher. So is the cost.
d)The productivity will depend on the scrapers (the pusher with idle time) which will be:
