Question

the number of songs purchased from an online music store on the first day the store open was 300,000. The number of songs purchased on day x after the first day is given by the expression 300,000 (1.008^n). each day the number of songs purchased is what percent greater than the number of songs purchased the preceding day?

Answer 1

To find this you simply have to look at the formula given. n stands for the number of days. 300,000 is the original. So the only number left is 1.008, but you have to make this a percent by moving the decimal to the right 2 places. 
Final answer is 100.8%
