A cellphone company plans to market a new smartphone. They have already sold 510 units during the first week of the campaign. They plan to increase sales by 12% each week. For example, they plan to sell about 571 units during week 2. They want to continue this for a year (52 weeks).
1. Write the values of the first term, the common ratio, and an expression for the recursive rule. Use the actual value of the common ratio in the recursive rule, not just “r”.
2. Write the explicit rule. How many phones will be sold during week number 37? Round the answer to the nearest whole number of cell phones.
3. Assume there are 52 weeks in a year. How many phones will be sold total during the entire first year? Write and evaluate the expression for the correct partial sum of the series. Round your answer to the nearest whole number.
Thanks to anyone who helps :)
