Question

Your friend asks you to help him study and will pay you 5 dimes the first time you help him. You agree to help if he multiplies your payment by 5 for each study session. After 2 study sessions, you will receive 25 dimes, and after 3 study sessions, you will receive 125 dimes.

Complete and solve the equation that finds the number of dimes he will pay you after the 7th study session.

= number of dimes for 7th study session

Payment for the 7th study session =
dimes

Answer 1

`x = {5}^(s)`

78,125 dimes

Step-by-step explanation:

if x equals the number of dimes given for the 7th study session and s equals the study session then make s equal seven since it's the seventh study session, 5 to the 7th power equals 78,125.
