On the first day of a social media ad campaign, a website had 15 unique visitors. Over the following several days, the website received three times the number of unique visitors as the previous day. The number of visitors, v, can be modeled by v=15⋅3(d−1), where dd is the number of days in the campaign. On which day of the ad campaign did the website have 10,000 visitors?

The membership fee at a sports club was $600 per year. Each year, the membership fee increased by 7%. The cost of membership, y, can be modeled by the equation y=600(1.07)x, where x is the number of years. How many years will it take for the cost of the membership to be $900? Choose the answer that gives the correct logarithmic equation and answer.
