Question

In your piggy bank, you dropped $1.00 on May 1, $1.75 on May 2, $2.50 on May 3 and so on until the last day of May. a) How much did you drop in the piggy bank on May 19? b) What is the total amount in your piggy bank at the end of May? Show all work.

Answer 1

A. $14.5 B. $23.5

Explanation:

You are adding .75 cents to your bank account each day so you can do .75 *18 days plus one dollar from day one to get $14.5 dollars on may 19. If you do 30 * .75 you get 22.5 plus a dollar from what you start with to get $23.5 at the end of may in your account. Hope this helped you!!
