Answer:
P(13,2) = 169
Explanation:
We have to calculate the combinations for left and right shoe considering is not the same having a right shoe blue and left red than having a right shoe rend and a left red.
there are 13 pairs from whcih she will take a single pair:

where:
n = number of pair = 13
r = shoes = 2 (one on each foot)

P(13,2) = 169
200,000,000(1.03)^70= 1,583,564,382
Answer:
Wages would fall due to an increase in labor costs.
When the workers compensation laws were not there, the employers only had to worry about one labor cost, that of paying their employees. With the introduction of worker's compensation, they then had to get insurance for their employees as well.
This led to an increase in the costs of labor which meant an increase in production costs and a decrease in profitability. To compensate for this, the employers cut wages in order to be able to pay for both the insurance and wages and still pay the same general amounts they were paying as wages such that their production costs don't rise significantly.
