Kylie starts with $145 in her piggy bank. each month she adds $20. which recursive function rule models the total amount in kylie’s piggy bank at the end of each month? an=145+an−1 and a1=20 an=145⋅an−1 and a1=20 an=20⋅an−1 and a1=145 an=20+an−1 and a1=145

Kylie's first month collection, a1= $ 145

Second month collection , a2= $145+ 20

Third month collection, a3  = $145 +2*20

.

.

.

.

so for n months collection = an-1+20

We get an= 20 + an-1  and a1=145

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.
