Answer 2

Margo will get 78,125 cents on Saturday.

Explanation:

Margo’s Dad offers to give her 5 cents on Sunday.

Then for each day of the week, he offers to give her 5 times the amount from the previous day.

This can be modeled as:
`5^(x+1)`

From Sunday to Saturday 6 days have elapsed, therefore she will have :

`5^(6+1)`

=
`5^(7)` = 78125 cents.

Hence, Margo will get 78,125 cents on Saturday.
