Jobie starts with $325 in her piggy bank. each month she adds $10. which recursive function rule models the total amount in jobie’s piggy bank at the end of each month? a). an=325⋅an−1 and a1=10 b). an=10+an−1 and a1=325 c). an=325+an−1 and a1=10 d). an=10⋅an−1 and a1=325

Hey there, just took the test from k12! the correct answer is in the pic below.

Hello, The answer is C.

Step-by-step explanation:

HOPE THIS HELPS :)

1- Rounding and determining the amount that needs to be borrowed:
Total amount needed = $203. Wen rounded, this will give us $200
Amount Quan has = $37. When rounded, this will give us $40
Now, we will get the amount that he needs to borrow as follows:
amount that he needs to borrow = 200 - 40 = $160

2- Inverse operation checking:
This means that we will work the problem frown bottom to up.
Quin has $40 (rounded) and he borrows $160 (rounded). This means that:
Total amount he has = 40 + 160 = $200 (the rounded amount needed)

Hope this helps :)
