Calculate the marginal cost of the 70th toy car produced. Round your answer to the nearest hundredth.

$1.43

Explanation:

A lot of information is missing, but i found a similar question. Hope it can help.

Labor    Q     Fixed          Variable   Total      Marginal       Average

4           70      50            120              170         1.43                2.43

5           82      50            150             200        2.50               2.44

marginal cost is calculated by dividing the incremental cost ($30) by the incremental output (21) = $30 / 21 = $1.4286 ≈ $1.43

explanation:

the answer is "b.the increased supply will create a surplus. "

the essential thought behind price controls is straightforward - utilize the power of law to modify the equilibrium of a market. for instance, the legislature may choose that the steel business needs to survive, and in this way pass a law to set a value floor on steel. this implies all steel sold must offer at or over the floor value, which must be set over the equilibrium cost for it to have any impact. the switch could likewise happen - the administration can choose that steel is excessively costly and set a value roof underneath its equilibrium value, with the goal that all steel must be sold at or beneath that ceiling.
