Juan was gifted a piggy bank for his birthday. he saves up $15 from his allowance in april, $23 in may, $31 in june and so on. how much will juan’s piggy bank contain at the end of 12 months?

He would have a total of $79 at the end of month 12. But, when you add the 15,23,31,etc it would be $423.

$819

Step-by-step explanation:

Well, how you would do this is that Juan gets 8+ the money he gets each month. So for June he would get $39, and July he would get $47, August he would get $55, September he would get 63$, October he would get $71, November he would get $79, December he would get $87, January he would get $95, February he would get $103, and March he would get $111. So, add all those up and you get $819.

Hope this helps!
