Answer:
28.85
Explanation
Keanu has decided to save a fixed amount of 70,000 for a given period. We would need to calculate the number of years to achieve 7,796,223 using the FVIFA formula (Future value interest for an annuity)
Fixed payment× FVIFA=Future value
<em>FVIFA</em> = 
where r is the periodic rate (9%)
and n is the number of periods
therefore; 70000×
=7796223
=(7796223×0.09)/70000
n=27.85
However, since Keanu will not invest until the end of the first year, he will spend 28.85 years to achieve his goal
Answer:
Price
The price in the short-run will decrease because with less marginal costs, producers would produce more goods and services which would shift the supply curve to the right. The new intersection with the demand curve will be at a lower price.
Quantity
As said above, producers would produce more goods and services which means that the quantity supplied will increase.
Profit
This is a competitive market. Each firm will earn zero profits because the drop in price will match the drop in marginal costs to ensure that firms are not making anything extra.
