Ijust want to make sure that this is correct:

kyle starts a fundraiser with 43 pennies. he recruits all of the players on his baseball team to participate. his goal is to triple the amount of pennies everyday. assume kyle meets his goal each day.
use x to represent the number of days and y to represent the total amount of pennies after each day.
enter an equation that represents this scenario in the box.

this is what i have:
y = 43 (3^x)
is this correct?
